recovering from an LVM failed disc and moving data back from Hot Spare

[Philippe Jouandeau]

Greetings,

Would you be able to provide me with the process and syntax to recover from an LVM disk failure where the data has been moved to a hot spare? The disc has been replaced and recovered to the OS (HP-UX 11.11) using fcmsutil on both nodes (ServiceGuard environment). I would like to use pvchange (OLR) to do a vgcfgrestore without interrupting the application and then move the data back from the spare volume which will resume as a hot spare.

The setup is two ServiceGuard L-Class servers fiber connected to two DS2405 JBOB (one mirrored of the other). The failed disc was seen through two paths on one host and two paths on the other host. I suspect that all LVM commands done to one host will have to be executed on the other host as well.

Thank you for your expert feedback.

ioscan, vgdetails attached....
check for /dev/dsk/c6t1d0

Thanks,

Philippe

pvmove will move the data and return the disk to being a spare.

Thanks Kevin,

pvmove will be executed on one node only, how will the other node know about the data move?
