To check the data types a storage pool is used for:

In Xsan Admin, select Volumes in the SAN Assets list and then click disclosure triangles m

in the list of volumes to show the storage pool of interest. Double-click the storage

pool in the list and look next to “Used For” in the Inspector window.

If the Capacity of a Larger LUN is Listed as 2 Terabytes

If a LUN that doesn’t yet belong to a storage pool is listed in Xsan Admin with a

capacity of 2 TB, even though you know it’s larger (which can happen if you used the

LUN with an earlier version of Xsan), try relabeling the LUN.

To relabel a LUN:

1 In Xsan Admin, select LUNs in the SAN Assets list.

2 Click LUNs, select the LUN in the list, and choose Remove LUN Label from the Action

(gear) pop-up menu.

3 With the LUN still selected, choose Change LUN label from the Action pop-up menu,

and enter a label.

If File Copying Doesn’t Finish

If the Ethernet connection to a metadata controller is lost, Finder le-copy operations

in progress on clients might not nish, even though the volume successfully fails over

to a standby controller.

To allow the copy operation to nish:

Reconnect the disconnected controller to the SAN’s Ethernet network. m

If a Volume Unexpectedly Restarts

Xsan can restart a volume in response to a variety of reasons, including controller

restart and volume failover. The notication is the same in all cases, but you can try

examining the log les to nd out more details.

To view the logs:

Open Xsan Admin and click the Logs button at the top of the window; then, in the m

Logs window that appears, use the Computer and Log pop-up menus to choose a log.
