Adding a Storage Pool to a Volume

You can add free space to a SAN volume by adding a storage pool to the volume.

If you’re expanding a volume that’s based on a built-in volume type, you can create a

new anity tag and add LUNs to it. Xsan Admin creates and organizes storage pools

within that tag for you. If you add LUNs to an existing anity tag, Xsan Admin lls out

any existing storage pool that has too few LUNs and, if there are enough LUNs, creates

storage pools for you.

If you’re expanding a custom volume, you create storage pools directly and add LUNs

directly to them.

Note: A volume can’t contain more than 512 storage pools.

To add a storage pool:

1 If necessary, connect the RAID systems that host the storage pool’s LUNs to the SAN

Fibre Channel network and power on the device.

2 In Xsan Admin, select Volumes in the SAN Assets list.

3 Select the volume in the list and choose Expand Volume from the Action (gear) pop-

up menu.

4 In the Label LUNs pane of the assistant, choose whether to label unlabeled LUNs

individually or sequentially based on a label prex.

If you use a label prex, Xsan Admin adds a number to the end of the prex to create

a label for each LUN. For example, if you use the prex “LUN,” your LUNs are labeled

“LUN1,” “LUN2,” and so forth. Already-labeled LUNs aren’t aected.

If you label LUNs individually, click Edit LUN Label on the next pane and enter a new

label.

5 In the Congure Volume Storage pane, click New Anity Tag (or New Pool) to add an

anity tag (or storage pool), and then drag LUNs to the new tag (or pool).

6 Click Continue to unmount and stop the volume, add the new storage, and remount

the expanded volume.

From the Command Line

You can also add a storage pool by modifying the associated volume conguration le

in Terminal. For more information, see the cvfs_config man page (% man -M

/Library/Filesystems/Xsan/man/ 4 cvfs_config) or “Xsan Conguration Files” on

page 12 2 .
