SHOW ACPI (Integrity servers only)

Displays the contents of Advanced Configuration and Power Interface (ACPI) tables and namespace structures.

Format

SHOW ACPI {/NAMESPACE |/TABLE}
[/ADDRESS = address | /ALL | /CHILDREN] [ident]


Parameter

ident

The name of the table or the namespace structure to be displayed. If an ident is given, /ADDRESS cannot be specified.

Qualifier

/ADDRESS = address

The physical address of the table entry or virtual address of a namespace structure to be displayed. If /ADDRESS is used, no ident may be specified.

/ALL

Specifies that detailed information on each entity is to be displayed. By default, only a brief summary of each entity is given, except when a specific table is displayed.

/CHILDREN

Specifies that all the child namespace structures for a specified namespace entry are to be displayed. /CHILDREN cannot be used with /TABLES.

/NAMESPACE

Specifies that ACPI namespace structures are to be displayed. Either /NAMESPACE or /TABLES must be specified.

/TABLES

Specifies that ACPI tables are to be displayed. Either /NAMESPACE or /TABLES must be specified.

Description

The SHOW ACPI command displays the Advanced Configuration and Power Interface (ACPI) Tables and Namespace structures, either as a one line summary for each entity or in detail. The amount of detail varies for each structure. The structures most interesting to OpenVMS are formatted; others are output as a hexadecimal dump.

SHOW ADDRESS

Displays the page table related information about a memory address.

Format

SHOW ADDRESS address [/PHYSICAL]


Parameter

address

The requested address.

Qualifier

/PHYSICAL

Indicates that a physical address has been given. The SHOW ADDRESS command displays the virtual address that maps to the given physical address.

Description

The SHOW ADDRESS command displays the region of memory that contains the memory address. It also shows all the page table entries (PTEs) that map the page and can show the range of addresses mapped by the given address if it is the address of a PTE. If the virtual address is in physical memory, the corresponding physical address is displayed.

When the /PHYSICAL qualifier is given, the SHOW ADDRESS command displays the virtual address that maps to the given physical address. This provides you with a way to use SDA commands that do not have a /PHYSICAL qualifier when only the physical address of a memory location is known.


Examples

#1

SDA> SHOW ADDRESS 80000000
FFFFFFFF.80000000 is an S0/S1 address
Mapped by Level-3 PTE at: FFFFFFFD.FFE00000 
Mapped by Level-2 PTE at: FFFFFFFD.FF7FF800 
Mapped by Level-1 PTE at: FFFFFFFD.FF7FDFF8 
Mapped by Selfmap PTE at: FFFFFFFD.FF7FDFF0
Also mapped in SPT window at: FFFFFFFF.FFDF0000
Mapped to physical address 00000000.00400000 
      

The SHOW ADDRESS command in this example shows where the address 80000000 is mapped at different page table entry levels.

#2

SDA> SHOW ADDRESS 0
00000000.00000000 is a P0 address
Mapped by Level-3 PTE at: FFFFFFFC.00000000 
Mapped by Level-2 PTE at: FFFFFFFD.FF000000 
Mapped by Level-1 PTE at: FFFFFFFD.FF7FC000 
Mapped by Selfmap PTE at: FFFFFFFD.FF7FDFF0
Not mapped to a physical address 
      

The SHOW ADDRESS command in this example shows where the address 0 is mapped at different page table entry levels.

#3

SDA> SHOW ADDRESS FFFFFFFD.FF000000
FFFFFFFD.FF000000 is the address of a process-private Level-2 PTE
Mapped by Level-1 PTE at: FFFFFFFD.FF7FC000 
Mapped by Selfmap PTE at: FFFFFFFD.FF7FDFF0
Range mapped at level 2: FFFFFFFC.00000000 to FFFFFFFC.00001FFF (1 page) 
Range mapped at level 3: 00000000.00000000 to 00000000.007FFFFF (1024 pages)
Mapped to physical address 00000000.01230000 
      

The SHOW ADDRESS command in this example shows where the address FFFFFFFD.FF7FC000 is mapped at page table entry and the range mapped by the PTE at this address.

#4

SDA> SHOW ADDRESS/PHYSICAL 0
Physical address 00000000.00000000 is mapped to system-space address FFFFFFFF.828FC000
      

The SHOW ADDRESS command in this example shows physical address 00000000.00000000 mapped to system-space address FFFFFFFF.828FC000.

#5

SDA> SHOW ADDRESS/PHYSICAL 029A6000
Physical address 00000000.029A6000 is mapped to process-space address 00000000.00030000 
(process index 0024)
      

The SHOW ADDRESS command in this example shows physical address 00000000.029A6000 mapped to process-space address 00000000.00030000 (process index 0024).


SHOW BUGCHECK

Displays the value, name, and text associated with one or all bugcheck codes.

Format

SHOW BUGCHECK {/ALL (d) | name | number}


Parameters

name

The name of the requested bugcheck code.

number

The value of the requested bugcheck code. The severity bits in the value are ignored.

The parameters name and number and the qualifier /ALL are all mutually exclusive.


Qualifier

/ALL

Description

The SHOW BUGCHECK command displays the value, name, and text associated with bugcheck codes.

Examples

#1

SDA> SHOW BUGCHECK 104
0100  DIRENTRY       ACP failed to find same directory entry
      

The SHOW BUGCHECK command in this example shows the requested bugcheck by number, ignoring the severity (FATAL).

#2

SDA> SHOW BUGCHECK DECNET
08D0  DECNET         DECnet detected a fatal error
      

The SHOW BUGCHECK command in this example shows the requested bugcheck by name.

#3

SDA> SHOW BUGCHECK   
BUGCHECK codes and texts
------------------------
0008  ACPMBFAIL      ACP failure to read mailbox
0010  ACPVAFAIL      ACP failure to return virtual address space

0020  ALCSMBCLR      ACP tried to allocate space already allocated
   .
   .
   .
      

The SHOW BUGCHECK command in this example shows the requested bugcheck by displaying all codes.


SHOW CALL_FRAME

Displays the locations and contents of the quadwords representing a procedure call frame.

Format

SHOW CALL_FRAME { [starting-address]
| /EXCEPTION_FRAME = intstk-address
| /NEXT_FRAME | /SUMMARY | /ALL}


Parameter

starting-address

For Alpha, an expression representing the starting address of the procedure call frame to be displayed. If no starting-address is given, the default starting address is the contents of the frame pointer (FP) register of the SDA current process. For a process that uses pthreads, the following SDA command can be used to display the starting addresses for all pthreads:


SDA> pthread thread -o u 

For Integrity servers, the starting address is an expression representing one of the following:

If no starting address is given, the default starting address is the invocation context handle of the current procedure in the SDA current process.


Qualifiers

/ALL

Displays details of all call frames beginning at the current frame and continuing until bottom of stack (equivalent to SHOW CALL and repeated execution of a SHOW CALL/NEXT command).

/EXCEPTION_FRAME=intstk-address

(Integrity servers only) Provides an alternate starting address for SHOW CALL_FRAME. intstk-address is the address of an exception frame from which SDA creates an initial invocation context and displays the procedure call frame.

/NEXT_FRAME

Displays the procedure call frame starting at the address stored in the frame longword of the last call frame displayed by this command. You must have issued a SHOW CALL_FRAME command previously in the current SDA session in order to use the /NEXT_FRAME qualifier to the command.

/SUMMARY

Provides a one-line summary for each call frame, including exception frames, system-service entry frames, ASTs, KPBs, and so on, until reaching the bottom of the stack.

Description

Whenever a procedure is called, information is stored on the stack of the calling routine in the form of a procedure call frame. The SHOW CALL_FRAME command displays the locations and contents of the call frame. The starting address of the call frame is determined from the specified starting address, the /NEXT_FRAME qualifier, or the address contained in the SDA current process frame register (the default action).

When using the SHOW CALL_FRAME/NEXT_FRAME command to follow a chain of call frames, SDA signals the end of the chain by the following message:


Cannot display further call frames (bottom of stack) 
This message indicates that the saved frame in the previous call frame has a zero value (for Alpha) or that the current frame is marked Bottom of Stack (for Integrity servers).

SHOW CLUSTER

Displays connection manager and system communications services (SCS) information for all nodes in a cluster.

Format

SHOW CLUSTER { [{/ADDRESS=n | /CIRCUIT=pb-addr | /CSID=csid | /NODE=name}] | /SCS }


Parameters

None.

Qualifiers

/ADDRESS=n

Displays only the OpenVMS Cluster system information for a specific OpenVMS Cluster member node, given the address of the cluster system block (CSB) for the node. This is mutually exclusive with the /CIRCUIT=pb-addr, /CSID=csid, and /NODE=name qualifiers.

/CIRCUIT=pb-addr

Displays only the OpenVMS Cluster system information for a specific path, where pb-addr is the address of its path block. This qualifier is mutually exclusive with the /ADDRESS=n, /CSID=csid, and /NODE=name qualifiers.

/CSID=csid

Displays only the OpenVMS Cluster system information for a specific OpenVMS Cluster member node. The value csid is the cluster system identification number (CSID) of the node to be displayed. You can find the CSID for a specific node in a cluster by examining the CSB list display of the SHOW CLUSTER command. Other SDA displays refer to a system's CSID. For instance, the SHOW LOCKS command indicates where a lock is mastered or held by CSID. This is mutually exclusive with the /ADDRESS=n, /CIRCUIT=pb-addr, and /NODE=name qualifiers.

/NODE=name

Displays only the OpenVMS Cluster system information for a specific OpenVMS Cluster member node, given its SCS node name. This is mutually exclusive with the /ADDRESS=n, /CIRCUIT=pb-addr, and /CSID=csid qualifiers.

/SCS

Displays a view of the cluster as seen by SCS.

Description

The SHOW CLUSTER command provides a view of the OpenVMS Cluster system from either the perspective of the connection manager (the default behavior), or from the perspective of the port driver or drivers (if the /SCS qualifier is used).

OpenVMS Cluster as Seen by the Connection Manager

The SHOW CLUSTER command provides a series of displays.

The OpenVMS Cluster summary display supplies the following information:

The CSB list displays information about the OpenVMS Cluster system blocks (CSBs) currently in operation; one CSB is assigned to each node of the cluster. For each CSB, the CSB list displays the following information:

For information about the state and status of nodes, see the description of the ADD CLUSTER command of the SHOW CLUSTER utility in the HP OpenVMS System Management Utilities Reference Manual.

The cluster block display includes information recorded in the cluster block (CLUB), including a list of activated flags, a summary of quorum and vote information, and other data that applies to the cluster from the perspective of the node for which the SDA is being run.

The cluster failover control block display provides detailed information concerning the cluster failover control block (CLUFCB). The cluster quorum disk control block display provides detailed information from the cluster quorum disk control block (CLUDCB).

Subsequent displays provide information for each CSB listed previously in the CSB list display. Each display shows the state and flags of a CSB, as well as other specific node information. (See the ADD MEMBER command of the SHOW CLUSTER utility in the HP OpenVMS System Management Utilities Reference Manual for information about the flags for OpenVMS Cluster nodes.)

If any of the qualifiers /ADDRESS=n, /CSID=csid, or /NODE=name are specified, then the SHOW CLUSTER command displays only the information from the CSB of the specified node.

OpenVMS Cluster as Seen by the Port Driver

The SHOW CLUSTER/SCS command provides a series of displays.

The SCS listening process directory lists those processes that are listening for incoming SCS connect requests. For each of these processes, this display records the following information:

The SCS systems summary display provides the system block (SB) address, node name, system type, system ID, and the number of connection paths for each SCS system. An SCS system can be a OpenVMS Cluster member, storage controller, or other such device.

Subsequent displays provide detailed information for each of the system blocks and the associated path blocks. The system block displays include the maximum message and datagram sizes, local hardware and software data, and SCS poller information. Path block displays include information that describes the connection, including remote functions and other path-related data.

If the qualifier /CIRCUIT=pb-addr is specified, the SHOW CLUSTER command displays only the information from the specified path block.

This example illustrates the output of the SHOW CLUSTER /SCS command.


SHOW CONNECTIONS

Displays information about all active connections between System Communications Services (SCS) processes or a single connection.

Format

SHOW CONNECTIONS [ {/ADDRESS=cdt-address | /NODE=name | /SYSAP=name } ]


Parameters

None.

Qualifiers

/ADDRESS=cdt-address

Displays information contained in the connection descriptor table (CDT) for a specific connection. You can find the cdt-address for any active connection on the system in the CDT summary page display of the SHOW CONNECTIONS command. In addition, CDT addresses are stored in many individual data structures related to SCS connections. These data structures include class driver request packets (CDRPs) and unit control blocks (UCBs) for class drivers that use SCS, and cluster system blocks (CSBs) for the connection manager.

/NODE=name

Displays all CDTs associated with the specified remote SCS node name.

/SYSAP=name

Displays all CDTs associated with the specified local SYSAP.

Description

The SHOW CONNECTIONS command provides a series of displays.

The CDT summary page lists information regarding each connection on the local system, including the following:

The CDT summary page concludes with a count of CDTs that are free and available to the system.

SHOW CONNECTIONS next displays a page of detailed information for each active CDT listed previously.
