Issue Description

The S5600 allocates two LUNs to the backup server and the VTL3605 allocates one ADIC Scalar1000 tape library and four IBM ILTO3 drives to the backup server.
1. The backup server can correctly identify LUNS allocated by the S5600.
2. The backup server cannot identify the tape library and drives allocated by the VTL3605.

Alarm Information


Handling Process

Step 1  Log in to the VTL management software.
Step 2  Find the backup server under the SAN Clients menu and see one tape library and four drives mapped to the backup server.
Step 3  Right-click the tape library icon and choose Properties.
Step 4  On the displayed dialog box, change the LUN value to 2 (value 2 indicates LUN0 and LUN1).
Step 5  Repeat steps 4 and 5 to change the LUN IDs of the four drives
Step 6  Scan for the hardware on the backup server and the VTL3605 is detected.

Root Cause

The IDs of LUNs mapped by the S5600 may be incompatible with the IDs of LUNs mapped by the VTL3605.
