• Before converting to a template volume, make sure that the standard volume contains all the data that is shared with the thin clones. • You cannot convert a volume to a template while it is a member of a collection. • Make sure that the standard volume has sufficient free space to hold the approximate amount of data that you write to each thin clone. For example, if the reported size of the template volume is 1GB, and in-use space is 900MB, you can write approximately 100MB to each thin clone before you must increase the thin clone size. To convert a standard volume to a template volume: 1. Click Volumes. 2. Expand Volumes and then select the volume name. 3. Click Convert to template. 4. Confirm that you want to convert the volume to a template volume. Create a Thin Clone To create thin clones from template volumes, you need the following information: • Clone name Name can be up to 63 bytes and is case-insensitive. You can use any printable Unicode character except for First and last characters cannot be a period, hyphen, or colon. 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. • Clone description (optional) Descriptions can be up to 127 bytes long. 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. • Storage space assignment: - Snapshot reserve setting - Thin-provisioning setting • Access control • Multihost access To create a thin clone from a template volume: 1. Click Volumes. 2. Expand Volumes and then select the template volume. 3. Click Create thin clone to open the Create Thin Clone - Volume Settings dialog box. 4. Type a unique name and, optionally, a description. 5. Click Next to open the Create Thin Clone - Space dialog box. 6. Change the snapshot reserve setting and the thin-provisioning settings. NOTE: If data reduction has been enabled on the volume, snapshot reserve is permanently disabled. 7. Click Next to open the Create Thin Clone - iSCSI Access dialog box. 8. Create an access control policy for the volume, select the permission (read-write or read-only), and specify the multihost access setting. 9. Click Next to open the Summary dialog box. 10. Click Finish if the thin clone configuration is correct. Click Back to make changes. Detach a Thin Clone from a Template Volume You can detach a thin clone from its template volume. Detaching a thin clone from a template volume breaks the dependency between the thin clone and the template volume. About Volumes 163
