Adding Volumes to a Volume Set You can add volumes to a volume set while the system is running. To add a volume to a system or nonsystem volume set, use the NEWVOL command. Once a volume is added to a volume set and initialized, the system recognizes the volume and the volume is ready for use. [REV BEG]
NOTE If the new volume is mounted, it must be in the SCRATCH or UNKNOWN state to be initialized and added to a volume set. It is possible to add a volume to a volume set even if that set is not mounted. Then when the volume set is mounted, it must be initialized using the INITVOL command before it can be used.
[REV END] Example: Adding Volumes to a Volume Set This example shows how to add a volume to a nonsystem volume set. 1. At the VOLUTIL prompt, use the DSTAT command to determine what volumes can be initialized. ___________________________________________________________ | | | | | volutil: :DSTAT | | | | LDEV-TYPE STATUS VOLUME (VOLUME SET - GEN) | | _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ | | 10-07937 MASTER MEMBER1 (PROD_SET-0) | | 11-07937 LONER | | 12-07937 SCRATCH | | | ___________________________________________________________ 2. LDEV 11 is a LONER volume and you determine it. It no longer contains any needed data. Since a volume needs to be in the SCRATCH or UNKNOWN state in order to be added to a volume set, change LDEV 11 to a SCRATCH volume by using the SCRATCHVOL command. Refer to chapter 5 for more information on this command. _______________________________________ | | | | | volutil: SCRATCHVOL 11 | | | _______________________________________ 3. To add the volume (LDEV 11) to PROD_SET, use the NEWVOL command. If you do not want to initialize the new volume, do not use the ldev parameter in the command. It is possible to add a volume and not initialize it (if you do not have a drive available). You can then initialize it when a drive is available. Refer to the INITVOL command described in chapter 5 of this manual. If you do not specify a volume class, the default class DISC will be assigned to the volume. The volume name can be up to 32 alphanumeric characters in length. The first character must be alphabetic. ____________________________________________ | | | | | volutil: NEWVOL PROD_SET:MEMBER2 11 | | | ____________________________________________ 4. The system responds with a question asking you to verify whether the information you input was correct. When you respond Y followed by Enter, the system displays process information. 5. After you have added a volume to a volume set, use the DSTAT command to verify that the volume was added to the volume set. _________________________________________________________________ NOTE A volume must be mounted in the LONER status before it can be SCRATCHED using the SCRATCHVOL command. _________________________________________________________________ ____________________________________________________________ | | | | | volutil: :DSTAT | | | | LDEV-TYPE STATUS VOLUME (VOLUME SET - GEN) | | _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ | | 10-07937 MASTER MEMBER1 (PROD_SET-0) | | 11-07937 MEMBER MEMBER2 (PROD_SET-0) | | 12-07937 SCRATCH | | | ____________________________________________________________ _________________________________________________________________ CAUTION Make sure you see the message verifying that the volume was initialized correctly. Any error that occurs during initialization means that the volume must be reinitialized. _________________________________________________________________ Once a volume has been added as part of a volume set, its name and volume ID are loaded on the master volume. This information cannot be deleted and remains there as long as the volume set exists.
NOTE A volume cannot be deleted from a volume set.
