Apple Xsan 2 (Third Edition) - Manual (Page 104)

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 file-copy operations
in progress on clients might not finish, even though the volume successfully fails over
to a standby controller.
To allow the copy operation to finish:
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 notification is the same in all cases, but you can try
examining the log files to find 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.
