Chapter 8 Solving SAN Problems 101

If You Can’t Mount a Volume on a Client

Try restarting the client computer, and then try again. Â

Check that all Fibre Channel cables are plugged in. Â

Make sure no other volumes are mounted on the client that have the same name as Â

the Xsan volume.

If You Can’t Unmount a Volume on a Client

Make sure no processes are using the volume. Â

Try restarting the client computer, and then try again. Â

If RAID LUNs Aren’t Accessible over Fibre Channel

Try restarting the computer that doesn’t see the LUNs. Â

Check the conguration of the Fibre Channel switch to be sure the SAN Â

components are in the same Fibre Channel zone.

If You Have Problems Using Command-Line Tools

If you get the response “insucient administrator privileges” when you run the

cvadmin 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 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 when you mix LUNs of dierent 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. You can use

Xsan Admin to rename the volume. For instructions, see “Renaming a Volume” on

page 62.
