Hello all,
the intended recreation of a HSG60 RAID set partition without touching
the others has been done now - without initializing the (whole) RAID set
as suggested in the DOC (surely missunderstood by me).
Many thanks to Alan Rollow from "dec.com" and Edward J. Branley !!
Here are the steps I took successfully
(the original question is appended below):
- Have HSG60 RAID set ("myraid") partition (number 5) that is to be
replaced by a smaller one beginning at the same position in
the RAID set.
The unit number will be the same. System is Tru64 V5.1 PK#2.
- mytrunix$ addvol /dev/disk/dsk18c myfiles.dom # adding a temp. spare
mytrunix$ rmvol /dev/disk/dsk17c myfiles.dom # removing the HSG partition
hsg60>>> SET d5 DISABLE_ACCESS_PATH=ALL
mytrunix$ hwmgr -scan scsi -bus 7 # device [7/0/5] cleared
hsg60>>> DELETE d5
hsg60>>> DESTROY_PARTITION myraid PARTITION=5
hsg60>>> CREATE_PARTITION myraid SIZE=16
hsg60>>> ADD UNIT d5 myraid PARTITION=5 DISABLE_ACCESS_PATH=ALL
NOWRITE_PROTECT
hsg60>>> SET d5 ENABLE_ACCESS_PATH=mytrunix1A1
mytrunix$ hwmgr -scan scsi -bus 7 # [7/0/5] reappears as dsk19
mytrunix$ disklabel -r /dev/rdisk/dsk19c
mytrunix$ disklabel -rw /dev/rdisk/dsk19c
mytrunix$ addvol /dev/disk/dsk19c myfiles.dom
mytrunix$ rmvol /dev/disk/dsk18c myfiles.dom # remove the temp. spare
- DO NOT "INITIALIZE myraid" after "DESTROY_PARTITION myraid PARTITION=5" !
- The controller configuration is stored in it's NVRAM.
- The "SAVE_CONFIGURATION" feature at RAID set initializing time will
instruct the HSG to save later configuration changes, too - to
accomplish a possible controller replacement.
My original question was:

Many thanks for your valuable help!
