About Solaris sd.conf file
The /kernel/drv/sd.conf file must have sufficient entries to allow for the dynamic import of snapshot devices. Snapshot devices are created when the backup starts, and must be made visible on the NetBackup client without restarting the operating system. Entries should be added to the sd.conf file for the persistent target numbers that were configured for the HBA.
Note:
The sd.conf file does not have to be modified if you use Leadville drivers.
Veritas recommends that you add LUNs 0-15 for all disk array targets on which snapshots are to be created. This creates 16 host-side LUNs on each target that can be used for importing the snapshots (clones, mirrors, and copy-on-write snapshots) required for backups. If 16 host-side LUNs are not enough for a particular disk array target, add more LUNs for that target. Note that snapshots are imported to a NetBackup client in sequential order starting with the lowest unused host-side LUN number. The host-side LUN number pool is managed on the disk array. The disk array cannot determine which host-side LUN numbers have been configured in sd.conf. The array can only determine which host-side LUN number it has not yet assigned to the host. If the array adds a device at a host-side LUN number that has not been configured in sd.conf, that device is not visible on the host. Also, if alternate client backups are being used, be sure to properly configure sd.conf on the alternate client.
You must restart after modifying sd.conf.
Symmetrix arrays pre-assign host-side LUN numbers (that is, the LUN numbers are not set at the time the device is imported). These pre-selected LUN numbers must be entered into sd.conf for the Symmetrix target number.
Note:
If you use EMC Control Center interface (ECC) to determine Symmetrix host-side LUN numbers, note that ECC shows host-side LUN numbers in hexadecimal format. Since the LUN entries in sd.conf must be in decimal format, convert the hexadecimal value to decimal before adding it to sd.conf.
If the Symmetrix array was persistently bound at target 5, and the host-side LUN numbers of the Symmetrix devices are 65, 66, 67, then the following entries should be added to sd.conf.
name="sd" class="scsi" target=5 lun=65;
name="sd" class="scsi" target=5 lun=66;
name="sd" class="scsi" target=5 lun=67;
