Since virtual devices do not represent actual physical resources, they can be
expanded as more storage is needed. The virtual device can be increased in size
by adding more blocks of storage from any unallocated space from the same
server.
Note that you will still need to repartition the virtual devices and
adjust/create/resize any file-systems on the partition after the virtual device is
expanded. Since partition and file-system formats are specific to the operating
system that the client is running, the administrator must perform these tasks
directly from the client. You can use tools like:
•
Partition Mag c
,
i
l
•
Windows 2000 Dynamic Disk
,
• or
Veritas Vo ume Manager
to add more drives to expand existing volume on-the-fly in real time (without
application down time).
Notes:
We do not recommend expanding a virtual device (SAN or NAS) while clients
are accessing the drives. However, when expanding an XFS resource, NAS
clients can remain connected.
