Creating a Volume Snapshot

To create a volume snapshot:

  1. Go to the Sun Web Console page and click SE6920 Configuration Service.
  2. Click Storage > Logical > Volumes.
  3. Click a volume name to view the Volume Details page for that volume.
  4. Click Snapshot.
  5. The New Snapshot wizard is displayed.

  6. Specify a name for the new volume snapshot, using a maximum of 16 characters.
  7. Valid characters include 0 to 9, A to Z and a to z, _ (underscore), and - (dash).

  8. Specify a description for the new volume snapshot, using a maximum of 256 characters, including spaces, and click Next.
  9. Valid characters include 0 to 9, A to Z and a to z, _(underscore), and -(dash), . (period), : (colon), , (comma), % (percent), ( ) (parenthesis), [ ] (brackets), { } (braces), ` (tick), ~ (tilde), and | (pipe).

  10. Specify the snapshot attributes and click Next.
  11. A volume can have up to eight snapshots if it has a snapshot reserve. Space is consumed in the pool only for data written to the volume after a snapshot is taken.

    The number of snapshots and amount of write activity you specify here together determine the size of the snapshot reserve. The number of snapshots that can actually be taken may be more or fewer than the number specified here if the write activity is less or more than anticipated.

    1. Select the number of snapshots you want used as the basis for calculating the pool size.
    2. Your selection here does not limit the number or snapshots you can create later.

    3. Select the level of snapshot write activity to the storage volume you want. The greater the amount of write activity, the more processing overhead is required.
  12. Select the initiators you want to map to the new snapshot.
  13. Review the specified information. If you are satisfied, click Finish. Otherwise, click Previous to make changes.
