Chapter 4 Managing SAN Storage 59
Changing Advanced Volume Settings
If your SAN volume has special conguration requirements, you can change the
standard volume settings when you create a volume. You can also change these
settings for an existing volume, with the exception of the block allocation size and
disabling the extended attributes option. (Once enabled, extended attributes can’t be
disabled.)
Note: To change a volume’s block allocation size or disable extended attributes,
you must destroy and recreate the volume.
To view or change volume settings:
Select Volume in the SAN Assets list, select the volume in the list, and choose Edit m
Volume Settings from the Action (gear) pop-up menu.
The following sections contain information about each setting.
Setting the Block Allocation Size
Xsan uses the volume block allocation size with the storage pool stripe breadth to
decide how to write data to a volume. If you create a volume based on a built-in
volume type (for example, General File Server or Podcast Producer Cluster), Xsan
Admin sets optimal values for you.
