Chapter 4, SAN Configuration for ServerFree Agent 57

Solaris only: Configure HBA Drivers for Offhost Backup

Fibre channel devices should be bound to specific SCSI target IDs by modifying the driver

configuration files for your host bus adapter (HBA). This binding ensures that the host

HBA and the third-party copy device are in agreement as to the target and LUN values for

each device. The binding also ensures that the target ID does not change after a system

reboot or after a fibre-channel reconfiguration. If the target ID changes, the offhost backup

configuration files (3pc.conf, mover.conf) will also be incorrect and will have to be

recreated.

The binding process is unique to each vendor and product. For assistance, refer to the

documentation provided for your HBA, or to the VERITAS support website. (See

“ServerFree Agent Information on the Web” on page xiv.) The binding requires the

fibre-channel world-wide port name.

Note Each time a device is added or removed, the binding must be updated to reflect the

new configuration.

If storage device SCSI target IDs are bound to world-wide port names in your HBA

configuration file, skip this section and go to “Create Offhost Backup Configuration Files”

on page 58.

▼ To configure HBA drivers on the media server:

1. If storage device target IDs are not already bound to world-wide port names, refer to

your “Device Checklist” on page 56 (filled out in the previous procedure) for the

world-wide names. Use the world-wide names to make the binding for each device.

2. Update your HBA configuration file by binding all SCSI device target IDs to their

associated world-wide port name.

For assistance with your particular HBA file, see “ServerFree Agent Information on

the Web” on page xiv.

3. Reboot the media server (reboot -- -r).

4. To ensure device visibility, repeat the steps described under “Verify NetBackup

Access to SAN Devices” on page 51.

When you are finished, the bptpcinfo command should list device pathnames and

serial numbers for all of your devices. Update the “Device Checklist” with those

values if needed.

5. Continue with “Create Offhost Backup Configuration Files.”
