XP and volume expansion
Does anyone know about non-disruptive volume expansion on XP disk arrays?
Thanks in advance.

Re: XP and volume expansion
here is the HP support document for Windows, LUN (LUSE) capacity expansion.
the host mode is 2C, and e.g. for the Windows MSCS cluster (basic disks), the recommendation is to bring the disk resource offline, expand it with LUSE and then diskpart it on the host size....

Re: XP and volume expansion
I am looking for any future plans to include it in microcode to support the expansion for non-LUSE volumes. If anyone heard any whispering word about it?

Re: XP and volume expansion
in Unix/Linux OS platform there is no real need for this, because they have LVM. Thus the LUNs can be nicely loadbalanced across all hardware paths from the host to the storage in smaller chunk. At the same the online extension is done via LVM on the host side:
e.g. in HP-UX it is valid for 11i v2, 11i v3:
http://h20000.www2.hp.com/bc/docs/support/SupportManual/c01920387/c01920387.pdf (BSC link updated by admin)
Windows does not have the LVM (maybe Veritas LVM) and thus the only method of the expansion is LUSE
XP has also the new feature of Thin Provisioning which aims in the EVA disk pool conceipt with the back-end redistribution in the future.
