Installation Guide 129
When there are only SCSI clients, the Move command that should place the cartridge to other cartridge
home position will be accepted.
• Check whether there should be a DAS or ROBAR client for the logical library used by the SCSI
client. If not, remove the unnecessary clients.
• If the DAS or ROBAR clients are not to be removed, use only the slots that are empty, but not the
home positions for the SCSI commands.
Issue: Executed on SCSI/FC client host the Test Unit Ready command returns Adapter status 1 <Failure> ,
although the adapter and connection with the Scalar DLC server are good.
Solution: Ensure that the library medium changer on the client host is disabled . See Disabling Library
Medium Changer on page 141.
Issue: After upgrading from 2.3 or 2.4 to 2.6 or 2.7, only one Target based on Fibre Channel adapter is
active. The SCSI clients assigned to the inactive targets cannot access the Scalar DLC.
Solution: There has been wrong Target-LUN mapping in older versions of Scalar DLC. The newest FC
target drivers allows only one target with 255 LUNs to be active on FC adapter operating in Target mode.
To activate the SCSI Clients assigned to the non-active SCSI targets again, do the following:
Step 1 Using the Management GUI > Configuration > SCSI Target tab, locate all FC adapters that
contain more than one Target.
Step 2 For each such FC adapter (for example, Adapter 1), locate the Target with minimal SCSI ID (for
example, Target 0). This will be the only active Target of the FC adapter.
Step 3 Under this active Target, create as many LUNs as there are non-active Targets at the Adapter
1.
Step 4 Using Configuration > Clients tab, create SCSI clients based on the LUNs of active Target 0.
Assign the logical library and check the Mode settings the same as they were for the non-active
clients. That means, for each client based on non-active target must be created the duplicated
SCSI client with same settings but based on the active Target (Target 0).
Step 5 Repeat Steps 1-4 for each FC adapter with multiple targets.
Step 6 After all SCSI clients are re-created, remove all SCSI clients based on non-active Targets and
non-active Targets with their LUNs.
Now the SCSI/FC clients can access their resources.
Note
The Management GUI will warn the admin if there will be an attempt to assign two
different clients (for example, DAS and SCSI) either to one logical library, or to different
logical libraries that has shared partitions. This assignment is not restricted, however.
Note
This issue typically appears only when the Scalar DLC client host operates under
Windows 2000 or 2003.
Note
This issue can appear after upgrading the Scalar DLC database from 2.3 or 2.4. In 2.5
the Target-LUN mapping is the same as in 2.6 and 2.7.
