Snapshot errors encountered with IBM4000 arrays (NetBackup status code 156)
The following table lists explanations and recommended actions for status code 156.
Table: Explanations and recommended actions for status code 156
Description and recommended action for status code 156
The array does not have enough free space.
FlashCopy logical drives are created under the same logical array as is the base or primary logical drive. The storage subsystem might have free space, but if the logical array has insufficient space, the FlashCopy operation fails.
The following messages may appear in the /usr/openv/netbackup/logs/bpfis log:
23:44:48.007  <2> onlfi_vfms_logf: INF - snapshot services: ibmdsfi:Wed Mar 12 2008 23:44:48.007721 <Thread id - 1> FlashCopy could not be created. command [create FlashCopyLogicalDrive baseLogicalDrive="angela_javelin_4" userLabel="angela_javelin_4_flcp_4";].23:44:48.012  <2> onlfi_vfms_logf: INF - snapshot services: ibmdsfi: FlashCopy creation failed for source volume angela_javelin_4 on storage unit ibmds4700.
In addition, the following messages may appear in /usr/openv/netbackup/logs/bpfis/ibmdsfi.log.date:
Mon Mar 31 2008 14:25:23.036588 <Pid - 1065104 / Thread id - 1> FlashCopy could not be created. command [create FlashCopyLogicalDrive baseLogicalDrive="drive-claix11-1" userLabel="drive-claix11-1_flcp";]. Mon Mar 31 2008 14:25:23.037164 <Pid - 1065104 / Thread id - 1> OUTPUT=[Unable to create logical drive "drive-claix11-1_flcp" using the Create FlashCopy Logical Drive command at line 1. Error - The operation cannot complete because there is not enough space on the array. The command at line 1 that caused the error is: create FlashCopyLogicalDrive baseLogicalDrive="drive-claix11-1" userLabel="drive-claix11-1_flcp";
Recommended action: Make sure that the array has enough space available for the snapshot.
The maximum number of FlashCopies (4) already exist on the array.

Error 129 - The operation cannot complete because the maximum number of flashcopy logical drives have been created for this base logical drive.
Recommended action: Delete any FlashCopies that NetBackup did not create.
The Access Logical Drive is not mapped for the NetBackup client or alternate client at LUN 31 or 7.
On the IBM DS4000, the Access Logical Drive communicates with the storage subsystem. Any client that is connected to and needs to communicate with the storage subsystem should have an Access Logical Drive mapped to it. If an Access Logical Drive is not mapped to the client, the client is unable to communicate with the array. As a result, any NetBackup client operation involving the array fails.
Recommended action: Create and map an Access Logical Drive. Contact IBM technical support or refer to your IBM array documentation.
The DAR driver is not functional.
Recommended action: Make sure that the RDAC package is installed on the AIX host.
