Apple Xsan 2 - Manual (Page 123)

Chapter 9 Solve SAN problems 123
The computer is on the same TCP/IP subnets as the other SAN components. (If Â
you’re using a private and a public Ethernet network, all SAN components must be
connected to both networks.)
The computer is connected to the SAN’s Fibre Channel networks.
Â
If you can’t mount a volume on a client
Restart the client computer, and then try mounting the volume again. Â
Check that all Fibre Channel cables are plugged in. Â
Make sure that no other volumes mounted on the client have the same name as the Â
Xsan volume.
If you can’t unmount a volume on a client
Make sure no processes are using the volume. Â
Restart the client computer, and then try unmounting the volume again. Â
If RAID LUNs aren’t accessible over Fibre Channel
Restart the computer that doesn’t see the LUNs. Â
Check the configuration of the Fibre Channel switch to be sure the SAN computers Â
and storage devices are in the same Fibre Channel zone.
If you have problems using command-line tools
If you get the response “insufficient administrator privileges” when you run the
cvadmin command-line tool, make sure you have root user privileges when you
use the tool. Log in as the root user or use the sudo command to run the tool.
For example:
$ sudo cvadmin
If a LUN doesn’t have as much space as expected
To make striping across all LUNs possible, Xsan adjusts LUN sizes to make LUNs in a
storage pool the same size as the smallest LUN in the pool. Xsan doesn’t use the extra
space on larger LUNs if you mix LUNs of different sizes in a storage pool.
If you can’t rename an Xsan volume in the Finder
Xsan doesn’t let a mounted Xsan volume be renamed using the Finder, but you can
use Xsan Admin to rename the volume. See “Rename a volume” on page 85.
