SAN Copy Target LUN not showing filesystem in LVM - Linux

Question

Platform: Linux RHEL4, CX3-40, FLARE 26

I am using SAN Copy to copy 3 LUNs from one array to another. I am unable to mount the target LUNs on the host. The error is: mount: Can't read superblock. Also, viewing the LVM gui, the LUNs appear, but without a file system.

I think I may be missing a step in the copy process. Does anyone have any experience with this that can give me a high level process?

Thanks
Sarah

Sarah,what was the status of SanCopy session when you tried to mount LUNs off the target array ? I would try this: 1) Let SanCopy finish it transfer.2) Once SanCopy target LUNs are presented to your target Linux host, reboot it.3) Try to vgimport/mount now let's say you need to do an incremental sancopy refresh1) unmount file system on target system2) export volume group3) perform sancopy transfer4) try to vgimport/mount

were u doing the san copy while the target disks were mounted/imported!!? Just a reimport should work..
