Can anyone tell me the steps to change a mirrored bad disk in hp ux??

refer to the following doc "When Good Disks Go Bad"

Hi taouw,

well, if you have OLR installed and disk is hot-swappable then, follow the below process.

1) pvchange -a n /dev/dsk/cXtYdZ

Now replace the bad disk

2) pvchange -a y /dev/dsk/cXtYdZ
3) vgcfgrestore -n /dev/vgXX /dev/rdsk/cXtYdZ
4) vgchange -a y /dev/vgXX
5) vgsync vgXX

Hi again,

The PDF given above my OLDSCHOOL is very good to go through for bad disk replacement. Go through it and you will get your queries answered.

@OLDSCHOOL,
Thanks i was also searching for the same link.

there is no vgcfgbackup????

I finally found it by going to google and using the following search:

when_good_disks_go_bad site: docs.hp.com

looked for about 10 minutes with the search tools at the docs site, generated too much fluff to weed through

"is there no vgcfgbackup?"

yes, there is. follow the applicable decision tree in the doc I linked.

Hi,
>>Can anyone tell me the steps to change a mirrored bad disk in hp ux??

1st you need to check is it root disk or other disk then according to the disk you need to proceed for disk change. best option is see the doc "When_Good_Disks_Go_Bad_WP.pdf"

there should be. check /etc/lvmconf directory to see if there is any configuration file exists for that VG.

Be aware - steps are different if you have SAS disk!
What server model do you have?
