NEC Storage NV series
This information is provided to help you use NetBackup for NDMP with an NEC Storage NV Series file server.
For more information on the NEC Storage NV Series, refer to the following documentation:
NEC Storage NV Series Software - Users Guide
NEC Storage NV Series Software - Maintenance Manual
For further details, contact NEC Corporation.
To enable the NDMP option Program Package (PP), use a browser to start the package installer. See the NEC Storage NV Series Software - Maintenance Manual for more details.
Robot
To find the robot device name, use the telnet command to log in to the NEC Storage NV system. Then run the following command:
dmesg | grep "scsi generic"
Example output:
Attached scsi generic sg0 at scsi0, channel 0, id 0, lun 0, type 8
The robot device is
/dev/sg0.Drives
To find the tape device names, log in to the NEC Storage NV system. Then enter the following:
dmesg | grep "scsi tape"
Example output:
Attached scsi tape st0 at scsi0, channel 0, id 1, lun 0 Attached scsi tape st1 at scsi0, channel 0, id 2, lun 0
The tape device names, to be entered on the Add Drive display in the NetBackup Administration Console, are
/dev/nst0for tape drive 1 and/dev/nst1for tape drive 2. Always use the drive names that begin with "n" because these are the non-rewinding devices.
The following directive must be placed at the start of the NetBackup policy'sBackup Selections tab (file list):
set XFS=yes
This directive must be specified for all NetBackup backups of the NEC Storage NV Series, otherwise the backup will fail. Note that the set XFS=yes directive must be specified for both XFS and XFSFW file systems.
To use snapshots for NDMP backups, add the following directive to the file list:
set SANPSHOT=y
To enable debugging for NDMP, log in to the NEC Storage NV Series and add the following lines to the /etc/sysconfig/ndmpd file:
LOGFILE=/var/dumpfile/ndmpd DEBUG=yes LEVEL=65535
Debug logs are located in the /var/dumpfile/ndmpd directory.
Known restrictions
The NEC Storage NV Series supports the NDMP protocol version V2 only.
The NEC Storage NV Series can back up only file systems, not subdirectories.
Only one backup or restore can be running per file system. For example, if a backup job is currently backing up
/export/sxfs/vol1, another attempt to back up or restore/export/sxfs/vol1at the same time will fail.A second backup of the same file system could fail if started too soon after the first backup of that file system. This is because a backup job needs time to delete the snapshot after completion of the backup. Until the snapshot is deleted, the second backup of the same file system cannot start. The same is true for restores: a restore of a file system could fail if started too soon after a previous restore of that file system.
