Chapter 3 Managing SAN Storage 49
Setting Storage Pool Access Permissions
You can set up storage pools for read-write or read-only access. Changing this setting
doesn’t damage existing data on the volume.
To set storage pool access permissions:
1 In Xsan Admin, select the SAN the storage pool belongs to, click Setup, and click
Storage.
2 Double-click the storage pool in the list.
3 Choose Read & Write or Read Only from the Permissions pop-up menu.
4 Click OK, then click Save.
From the Command Line
You can also set read or write access to a storage pool using the
cvadmin enable
command in Terminal. For more information, see the cvadmin man page or “Viewing or
Changing Volume and Storage Pool Settings (cvadmin)” on page 85.
Choosing the Types of Files Stored on a Storage Pool
You can limit the files that are stored on a particular storage pool to volume journal
data and metadata, user data, user data with an affinity for that storage pool, or a
combination of these.
Journal data and metadata are always stored on the first storage pool in a volume.
To choose the data types for a storage pool:
1 In Xsan Admin, select the SAN the storage pool belongs to, click Setup, and click
Storage.
2 Double-click the storage pool in the list.
3 Next to Use For, choose the data types to store on the storage pool.
4 Click OK, then click Save.
