Example
If you are using RHEL 3 and have a local SCSI drive, you must use the following process so that the
SRP driver can discover multiple LUNs in the correct order.
Scenario
1.
Determine if your set-up requires the special procedure:
•
You are running RHEL 3
•
Your host has a local SCSI drive
•
You have installed an InfiniBand HCA in your host
•
You have installed the SRP protocol
•
The SRP initiator is communicating with a target that has multiple LUNs (for example LUN 0
and LUN 1)
If the above description fits your scenario, the SRP driver will start and discover the LUNs.
However, it will discover only LUN 0. Use the steps below to discover the LUNs in the correct
order.
2.
Rescan the SRP targets from the host to discover all the LUNs.
Note: If you have multiple targets with multiple LUNs, the LUNs will be discovered in the wrong
order. Instead of all the LUNs on one device being discovered first (LUN 0, LUN 1, etc), LUN 0 on
the first target will be discovered, then LUN 0 on the second target will be discovered.
