To recover an optical or tape volume:

1. Enter the following RECOVERY command:

   F OAM,START,RECOVERY,volser,BACKUP1

   where volser is the volume serial number of one of the volumes that is being recovered.

   If more than one backup copy of the objects exists, you can select whether to use the first or second backup copy for the recovery by specifying BACKUP1 or BACKUP2 on the F OAM,START,RECOVERY command when recovering a PRIMARY volume. If you omit BACKUP1 and BACKUP2, OAM recovers the first backup copy of the object by default.

   To recover a primary volume, all of the backup volumes containing backup copies of the object on the primary volume are needed whether they are optical or tape. Also, to recover a backup volume, each Object storage group must be searched for objects that have a backup copy on the backup volume to be recovered. For each of these objects, the primary copy is used to recover the backup volume. The primary copy of these objects could be on disk (DB2 or file system), optical, or tape. The Volume Recovery utility must identify the optical and tape volumes that are needed for the recovery.

   Requirement: The RECOVERY command has the following requirements:

   • The optical or tape volume that is specified on the command is not controlled by another OAM within the OAMplex.
   • Unmounted shelf-resident volumes must be available to the instance of OAM on which the command was entered.

   If the member name associated with the optical or tape volume serial number specified on this command is not the member name for this instance of OAM, the command fails. OAM issues message CBR1068I.

2. The system issues the following messages:

   CBR1000I OAM START command execution scheduled.
    
   CBR9800I  OAM Volume Recovery starting for volumes volser1 and volser2.
    
   CBR9827I  OAM Volume Recovery. The following TAPE volumes are needed
             for recovery: volser1 volser2 volser3 volser4 volser5
             volser6 volser7 volser8 volser9
   
   CBR9824I  OAM Volume Recovery. The following OPTICAL volumes are needed
             for recovery: volser1 volser2 volser3 volser4 volser5
             volser6 volser7 volser8 volser9.

   Message CBR9800I indicates that volume recovery has started for volumes volser1 and volser2. In situations where a tape volume is being recovered, volser2 is labeled as N/A.

   Message CBR9824I gives you a list of optical volumes to retrieve that are identified by volser-n. This message allows you to get the optical volumes that are needed for recovery processing.

   Message CBR9827I gives you a list of tape volumes to retrieve that are identified by volser-n. This message allows you to get the tape volumes that are needed for recovery processing.

   _______________________________________________________

3. For the volumes listed in messages CBR9827I and CBR9824I, the system issues the following message:

   CBR9810D  Reply ‘QUIT’ to terminate or ‘GO’ to proceed with recovery.

   _______________________________________________________

4. If all the volumes are not available, reply QUIT to terminate recovery, and start again when the volumes have been retrieved.

   If you reply QUIT to CBR9810D, the system issues the following messages:

   CBR9862I Volume Recovery status for volumes volser1 and volser2 is not available.
   CBR9819I OAM Volume Recovery is ending for volumes volser1 and volser2

   _______________________________________________________

5. If the volumes are available, reply GO to CBR9810D.

   _______________________________________________________

6. The system issues the following message for each optical volume listed in message CBR9824I:

   CBR4400A Mount volume volser on drive drive-name. 
    Shelf location is shelfloc.

   _______________________________________________________

7. The system issues the following message for each tape volume that is listed in the message CBR9827I:

   IEC501A M drive-Addr,volser,label,,,,data_set_name.

   Message CBR9824I might identify volumes that are either library-resident or shelf-resident optical volumes. The system automatically mounts the library-resident optical volumes; therefore, a mount message is not issued for them. The mount message CBR4400A requests only shelf-resident optical volumes for recovery.

   _______________________________________________________

8. Mount the optical volume that is identified by volser in message CBR4400A and any tape volumes identified by volser in message IEC501A.

   When recovery is complete, the system issues the following message:

   CBR9819I OAM Volume Recovery is ending for volumes volser1 and volser2
