Issue



FlashBackup-Windows or Virtualization restores using the touch file ALT_RESTORE_COPY_NUMBER persist in requesting the original primary copy.


Error



Review of the log files will show that everything in the restore appears to be fine until bpdm requests the storage unit information from bpdbm.  

Example:

The bpdm log file will show the call to bpdbm:

15:22:00.059 [27335] <2> logconnections: BPDBM CONNECT FROM 10.0.0.1.48654 TO 10.0.0.1.1556 fd = 9
 

The bpdbm log will show receipt of  the call:
15:22:00.064 [27336] <2> logconnections: BPDBM ACCEPT FROM 10.0.0.1.48654 TO 10.0.0.1.1556 fd = 10
 

The bpdbm process will execute a SQL statement to fetch the storage unit information, but it always returns the original storage unit:

15:22:00.135 [27336] <2> fetch_DBM_Image: umeExpiration=0, PfiType=0, ImageAttribute=0, Creator='root', ScheduleName='Full', ProxyClient='', KeywordPhrase='', FilesFile='Any_VMPOLICY_1390115095_FULL.f', FilesFileSize=18161177, SoftwareVersion='', [cut],
StorageServiceName='any_stu_copy1', [cut]

Note that in the output the copy 1 storage unit is returned. in the StorageServiceName information, in this case 'any_stu_copy1'

The bpdm log file then shows the @aaaaa media id versus the actual copy 2 media.

15:22:00.150 [27335] <2> log_frag_info: frag 1 file 0 of @aaaaa has blocks 0 to 53813525 for anyclient.my.domain_1390115095
15:22:00.151 [27335] <2> read_backup: file @aaaaa, copy 1, fragment 1 (26906763 Kbytes) being considered for read-blockmap
 

Since the stu/media doesn't exist in this particular example environment, the restore exits with 2067.
15:22:00.392 [27335] <2> RequestInitialResources: returning
15:22:00.393 [27335] <4> nbjm_media_request: Error from RequestMultipleResources, Master my_master, error 2067,
resourceAllocated 0
 

 


Environment



This can affect images created by NetBackup FlashBackup-Windows, VMware, and Hyper-V policies. This will also impact the bprestore command when using the -copy option to specify a non-primary copy.

 


Solution



Workaround:
The workaround is to change the primary copy of the backup ID required for a restore to the required copy, normally copy 2.  For example, to change copy 2 of just one specific <backupid> to be primary, use either of these from C:\Program Files\VERITAS\NetBackup\bin\Admincmd:
 
bpchangeprimary -copy 2 -id <backupid>
-or-
bpduplicate -npc 2 -backupid <backupid>
 
NOTE: Running the above commands without specifying a backup id as it will change every image that has 2 or more copies.
