Using DSCLI commands to obtain unique IBM identifiers
The NetBackup policy requires entry of the array's Unique ID. If your array administrator provided LUN numbers for the devices, you must convert those LUN numbers into unique IDs for entry in the NetBackup policy Snapshot Resources pane. You can obtain the LUN unique IDs in either of two ways, as described in this topic.
The LUN ID of the primary and snapshot (clone) logical volume can be found from the array by means of DSCLI commands or the IBM Storage Manager interface.
To use DSCLI commands to obtain unique IBM identifiers
- Find the host connection and its corresponding volume group by entering the following:
lshostconnect -dev enclosure_ID
Example:
dscli> lshostconnect -dev IBM.1750-6866123 Date/Time: December 17, 2007 4:18:02 PM IST IBM DSCLI Version: 5.2.2.224 DS: IBM.1750-6866123 Name ID WWPN HostType Profile portgrp volgrpID ESSIOport ====================================================================================== oigtsol05 0000 10000000C956A9B4 Sun SUN - Solaris 0 V11 all oigtaix03 0022 10000000C969F60E pSeries IBM pSeries - AIX 0 V46 all oigtaix02 0023 10000000C94AA677 pSeries IBM pSeries - AIX 0 V47 all
- Find the volumes presented to this volume group and to the host:
showvolgrp -dev enclosure_ID volume_group
Example:
dscli> showvolgrp -dev IBM.1750-6866123 V47 Date/Time: December 17, 2007 4:21:01 PM IST IBM DSCLI Version: 5.2.2.224 DS: IBM.1750-6866123 Name oigtaix02 ID V47 Type SCSI Mask Vols 0002 0003 0004 0005 0006 0007 0008 0009 0031
The values listed for Vols are the LUN ids.
- Find out which device on the host corresponds to a given logical volume.
Enter the following:
/usr/openv/netbackup/bin/nbfirescan
To use the IBM Storage Manager web interface to obtain the device identifiers
- In the Storage Manager, click Real-time manager > Manage hardware > Host systems.
- Click the host for which you need to find the volumes presented.
The volume groups that are associated with the host are displayed.
- Click the volume group to get the list of the logical volumes that are configured in this volume group.
The Number column indicates the LUN ID.
