HPUX RAID 1 COnfiguration

Hi Guys, Question is - how do you go about repairing a software RAID 1 set on a HPUX server when a drive fails and is replaced. I have swapped out the disk, but it doesn't seem to auto rebuild.
Thanks,

Re: HPUX RAID 1 COnfiguration

RAID concepts are usually associated with specialized hardware. If by the term Software RAID, you are referring to Mirror/UX, then you need to follow the disk replacement guide (attached). There is no auto-rebuild for software mirroring. Pay special attention to the instructions if the bad disk is part of your boot disk set.

Re: HPUX RAID 1 COnfiguration

Hi Justin

For repairing software RAID use

#vgsync
#lvsync

For details check man pages of vgsync, lvsync

Re: HPUX RAID 1 COnfiguration

Hi Guys, Thanks for all the responses. I have run the vgcfgrestore etc OK, but when I run the vgsync I get the below output. Any Ideas?

Thanks,
