Creating a Snap Pool Before you can convert a standard volume to a master volume or create a master volume for snapshots, a snap pool must exist. A snap pool and its associated master volumes can be in different virtual disks, but must be owned by the same controller. You can create a maximum of 16 snap pools. To create a snap-pool volume: 1. Select Manage > Volume Management > Snapshot Services > Create Snap-Pool. For each virtual disk, the virtual disk panel shows a status icon; the name, RAID level, size, number of disk drives, and number of volumes; and utility status, if any. 2. Select a virtual disk. The selected virtual disk's volume names, sizes, and types are displayed, and the amount of free space. 3. Type a size in Mbyte for the snap pool. For information about estimating the snap pool size, see "Estimating Snap-Pool Size" on page 105. 4. (Optional) Change the name for the new snap pool. The default name is vdisk-name_SPnumber. For example, MyVdisk_SP1. In a later step, you will associate a master volume with this snap pool. Name the snap pool in such a way that it can be easily identified with the correct virtual disk. The name is case sensitive and can include 20 characters, but not comma, quotation mark ("), or backslash. Note - If the default name exceeds 20 characters it will be truncated. 5. Click Create Snap Pool. When processing is complete, a message indicates whether the operation succeeded. If the operation succeeded, the new snap pool is displayed in the Volume Menu panel. You should now configure notification thresholds and policies for the snap pool; see "Setting Snap Pool Policies and Thresholds" on page 110. Chapter 3 Managing Storage 109
