This issue was initially reported in 6.5.2 and documented in TECH128805 - bpbkar32.exe faults on the inactive node of a Windows 2008 cluster (linked below).
It was formally resolved in 126.96.36.199 with the aid of a new -ignore_unresolved_volumes switch for w2koption.
However, starting in 7.5 GA, although the w2koption command still exists and runs without error, it no longer prevents a Shadow Copy Components backup from attempting to snapshot the absent volume.
Activity Monitor = Status Code: 156
The below snips come from bpbkar captured using Client side logging at General Level 2:
It acknowledges that the correct w2koption command was run correctly:
11:02:51.712 AM: [2076.2516] <2> tar_base::V_vTarMsgW: WRN - You have chosen to ignore unresolved volumes for Shadow Copy Components backups. Your backup will exit status zero even if the following volumes cannot be resolved E:
However, upon discovering the unresolved volume, the job ends with Status Code 156:
11:03:02.243 AM: [2076.2516] <2> ov_log::V_GlobalLog: INF - Status E_FS_VOLUME_NOT_FOUND (0xE0000352) for object 'System Files'. Faild to resolve volume path name for 'e:\program files\symantec\netbackup dlo\' in SHADOW::SetSelectedForBackup
11:03:02.243 AM: [2076.2516] <2> tar_base::V_vTarMsgW: ERR - Volume resolution error for (System State:\System Files\System Files)
11:03:02.259 AM: [2076.2516] <2> tar_base::V_vTarMsgW: INF - EXIT STATUS 156: snapshot error encountered
The formal resolution for this issue (Etrack 3013200) is included in the following release:
- NetBackup 7.5 Maintenance Release 5 (188.8.131.52)
NetBackup 184.108.40.206 is now available - please access the Related Article below for more information.
Once the problem host has been upgraded with the maintenance release, the NetBackup Client Agent will again properly respond to w2koption -backup -ignore_unresolved_volumes and ignore the identified absent volume(s).
Note: This hotfix is no longer publicly available, as all of its fixes are included in the NetBackup 220.127.116.11 Maintenance Release. If any of these issues are experienced in a NetBackup 7.5.0.x environment, the supported resolution is to apply the maintenance release.
