[Veritas-vx] vxvm failed to import 2T vm disk

[Carl E. Ma]

Hello,

We are running Veritas Volume Manager 5.1SP1 on solaris 10 and experiencing problem to import one 4TByte disk group, which has two concatenated 2T disks.

The alerts(on our Veritas Operations Manager console when rebooting server) are "disk asm_25000_33 import failed". After server up, I can import disk group WITHOUT problem. It just failed to import disks when server reboot. I am not sure whether the problem is related to disk size or active-active array path.

I initialized both disks as EFI disk with sliced format.

bash-3.00# vxdisk list | grep ams_25000
ams_25000_32 auto:sliced - - online
ams_25000_33 auto:sliced - - online

Both SAN disks have two active paths.

bash-3.00# vxdisk list ams_25000_32
