Dynamic LUN Expansion

10 VERITAS Volume Manager Hardware Notes

If the device that is being resized has the only valid configuration copy for a

disk group, the -f option may be specified to forcibly resize the device.

Resizing a device that contains the only valid configuration copy for a disk

group can result in data loss if a system crash occurs during the resize.

Resizing a virtual disk device is a non-transactional operation outside the

control of VxVM. This means that the resize command may have to be re-issued

following a system crash. In addition, a system crash may leave the private

region on the device in an unusable state. If this occurs, the disk must be

reinitialized, reattached to the disk group, and its data resynchronized or

recovered from a backup.
