I've just installed an Overland TapeXpress L490/L490E onto an ES40 running
Tru64 Unix V5.1. (The L490/L490E is a 10-cartridge 3480/3490 tape library
that is virtually identical to a TKZ62.)
Upon rebooting the system the O/S dutifully created a device special file
called /dev/changer/mc0. However attempts to access this device using, for
example, the mt command, are failing. For example:
mt -f /dev/changer/mc0 rewind
yields the message:
/dev/changer/mc0 rewind 1 failed: no such device or address
mt -f /dev/changer/mc0 status
gives a bunch of stuff and then ends with an ominous:
mtiocget ioctl failed!
If I do an hwmgr -v dev I see a promising entry of:
105: /dev/changer/mc0 L490E bus-4-targ-5-lun-0
Furthermore, a scu show edt shows the following hopeful information:
Bus/Target/Lun Device Type ANSI Vendor ID Product
ID Revision N/W
----------------------
----------------- --------- --------------------
------------------ --------------------
4 5 0 Sequential SCSI-2 OVERLAND L490E
0756 W
4 5 1 Changer SCSI-2 OVERLAND L490E 0756 W
I've seen various references in the archives about a ddr.dbase file needing
to be properly populated as well as the mcutil utility. I don't have any
entry in ddr.dbase that would seem appropriate; all attempts to get the
mcutil to work have failed. For example, if I do a:
mcutil -m s:0 s:1
I get the message:
mcutil: cannot find this entry in mcicap or $MCICAP
According the the man pages, since I didn't specify which device to use
it'll default to /dev/changer/mc0. Note that a:
file /dev/changer/mc0
dutifully reports the following:
/dev/changer/mc0: character special (19/389) SCSI #4 "L490E" special_device
#0 (SCSI ID #5) (SCSI LUN #0)
Holy confusion batman! Note that all I really need to be able to do is get
the mt command to work. We've written scripts for an existing TKZ62 (Tru64
Unix V4.0D) that do everything we need.
Any help would be outrageously appreciated!
regards,
Chris
