1. Click Volumes. 2. Expand Volumes and then expand the volume name. 3. Select the snapshot timestamp. 4. In the Activities panel, click Modify snapshot properties to open the dialog box. 5. In the General tab, type the new snapshot name and, optionally, a description. 6. Click OK. NOTE: Snapshot names can be up to 127 characters. Fewer characters are accepted for this field if you type the value as a Unicode character string, which takes up a variable number of bytes, depending on the specific character. Modify the Snapshot Alias You can modify the public alias (public name) for a snapshot. Some iSCSI initiators show the alias along with the iSCSI target name. The alias can help you identify the snapshot. If the alias is used with an iSCSI connection, the alias name follows the volume name. 1. Click Volumes. 2. Expand Volumes and then expand the volume name. 3. Select the snapshot timestamp. 4. In the Activities panel, click Modify snapshot properties to open the dialog box. 5. Click the iSCSI tab. 6. Type the new alias in the Public alias field. Alias names can be up to 54 ASCII characters. 7. Click OK. Modify Snapshot Permission A snapshot can have read-only or read-write permission. The following considerations apply: • If you write to a snapshot, it might no longer represent the contents of the base volume at the time of snapshot creation. • To change the permission of an online snapshot to read-only, first set the snapshot offline. To modify the permission for a snapshot: 1. Click Volumes. 2. Expand Volumes and then expand the volume name. 3. Select the snapshot timestamp. 4. In the Activities panel, click Set access type. The Select Access Type dialog box opens. 5. Select the permission for the snapshot (either Set read-write or Set read-only). 6. If your environment supports multiple initiators accessing a volume, you can check the Allow simultaneous connections from initiators with different IQNs checkbox. This option is disabled by default. 7. Click OK. Delete Snapshots You can delete unwanted snapshots. If you delete a snapshot that is part of a snapshot collection or a custom snapshot collection, the collection's Integrity status changes to incomplete. NOTE: You must take a snapshot offline before you can delete it. To take the snapshot offline, click the snapshot's timestamp and click Set snapshot offline in the Activities panel. 1. Click Volumes. 2. Expand Volumes. 3. Expand the volume name and select the snapshot timestamp that you want to delete. 230 About Backing Up and Protecting Your Data
