Replace Root Mirror disk on RX6600 Server
I have rx6600 server having 146 GB x 4 disks and two disks are mirror of other two disks using mirror software and both mirror copies are part of one VG00.
Now the issue is the error message is reported in syslog for I/O error on disk path 0_4_1_0.0.0.2.0 which is part of vg00 and I need to replace the disk. Physically the disk status is good and error message not repeated again in last 24 hours but for CU satisfaction I need to replace.
Can anyone share me the procedure how to identify and replace the root mirror disk in rx6600 server.
Thanks in Advance.
Khalid

Re: Replace Root Mirror disk on RX6600 Server
# sasmgr replace_tgt -D /dev/sasd0 -q old_tgt=/dev/dsk/c3t2d0 -q new_tgt_hwpath=0/4/1/0.0.0.1.0
you need to do the "standard" steps, see

Re: Replace Root Mirror disk on RX6600 Server
What I understand is first I have to update the path using sasmgr replace_target and then
Use vi to create a partition description file by doing the following:
# vi /tmp/partitionfile
The 4 line entry for 11.23 should look like this:
3
EFI 500MB
HPUX 100%
HPSP 400MB
# idisk -wf /tmp/partitionfile /dev/rdsk/cXtXdX
Use insf to create the new device dfiles (cXtXdXs1, cXtXdX2 and cXtXdXs3)
# insf -e
Use mkboot to format and populate the newly created EFI partition:
# mkboot -e -l /dev/dsk/cXtXdX
# pvchange -a n /dev/dsk/cXtXdXs2
# vgcfgrestore -n vg00 /dev/rdsk/cXtXdXs2
# pvchange -a y /dev/dsk/cXtXdXs2
# vgchange -a y vg00
# vgsync vg00
# lvlnboot -r /dev/vg00/lvol3 /dev/vg00
# lvlnboot -b /dev/vg00/lvol1 /dev/vg00
# lvlnboot -s /dev/vg00/lvol2 /dev/vg00
# lvlnboot -d /dev/vg00/lvol2 /dev/vg00
# lvlnboot -v (to verify the results)
Is that├в s oky or something I am missing ?

Re: Replace Root Mirror disk on RX6600 Server
1. Deactivate the failed disk
# pvchange -a n /dev/dsk/cxtxdxs2
2. Confirm the failed disk (eg: here we use sas bay 1)
# sasmgr get_info -D /dev/sasd0 -q lun=all -q lun_locate
# sasmgr get_info -D /dev/sasd0 -q raid
3. Turn on the LED indicator of the failed disk for replacing
# sasmgr set_attr -D /dev/sasd0 -q lun=/dev/rdsk/cxtxdx -q locate_led=on
# sasmgr get_info -D /dev/sasd0 -q lun=all -q lun_locate
Once disk replaced, follow the following procedure
