I have a RP4440 running 11.23. The Primary root disk has failed, it is running of the mirror.
ioscan -fnCdisk (which took ages) shows:
disk 36 0/1/1/0.0.0 sdisk NO_HW DEVICE HP 73.4GST373454LC
/dev/dsk/c2t0d0 /dev/rdsk/c2t0d0
disk 1 0/1/1/0.1.0 sdisk CLAIMED DEVICE HP 73.4GST373454LC
/dev/dsk/c2t1d0 /dev/rdsk/c2t1d0
syslog entry, which is coming out repeatedly
Jan 10 11:57:12 SERVER_NAME vmunix: SCSI Ultra320 0/1/1/0 instance 2: IO Type : MPT Domain Validation IO has timed-out. Target ID: 0, LUN ID: 0. Inquiry Command - CDB: 12 00 00 00 40 00
I have raised a call for a replacement. What do I have to do before or after the disk is replaced?
Thanks
Tariq

Re: Replace primary root disk in rp4440 HP-UX 11.23
Could someone provide a step by step guide to replace the failed disk:
The failed disk is:
/dev/dsk/c2t0d0
Server is running on mirror:
/dev/dsk/c2t1d0
I have tried to follow the when good disks go bad doc, but find it a little confusing.
Basically I need step by step.
Regards
Tariq

Re: Replace primary root disk in rp4440 HP-UX 11.23
it will work ..as i used it many times.
The thing is to attach and detach the disk with
pvchange command ,which works if there are
OLAR patches installed as mentioned in
the doc "when good disk go bad"
Thanks
Mani
Happy to help !!
