Troubleshooting
Issue
: After upgrade from 2.4 or earlier, and Scalar DLC reconfiguration (see above), the customer
application based on FC Target still cannot access the Scalar DLC.
Solution
: Scalar DLC version 2.3 and 2.4 have been released with the old Target driver microcode that
uses auto-mapping LUN-to-Target engine. In Scalar DLC 2.5 and later, the new SCSI/FC Target microcode
permits only manual mapping; automapping is not permitted.
Some backup applications can recover and continue to function, while others may need manual adjustment
and reconfiguration. If your application cannot access Scalar DLC after the SCSI Targets are reconfigured,
you may need to reconfigure your backup application, too.
Force Restart
Issue:
The installation of Scalar DLC or another software package is finished, the dialog like “Your system
is to be restarted now, press “yes’ to restart PC“ appears. But after pressing “yes” button the dialog vanished
and the restart is not initiated.
Solution:
Ikernel.exe
object hangs. Stop it manually via Windows Task Manager (Processes > Ikernel.exe
(right-click) > End Process). After the IKernel is stopped, restart the PC manually via
Start > Shutdown >
Restart
.
Scalar DLC Force Removing
Sometimes removing the Scalar DLC by its standard way, as described in
Add/Remove Scalar DLC
Software
on page 77, is not possible.
Issue:
SQL server is stopped, Scalar DLC repair/update/remove fails.
Solution:
Start the SQL Server Agent manually and then repeat the repair/update/remove operation.
Issue:
RAID permanently goes to unplugged mode, MS SQL server cannot be started, Scalar DLC
database cannot be accessed, Scalar DLC cannot be removed.
Solution:
First remove SQL server, then remove Scalar DLC.
Step 1
Remove SQL server from Node 1 (
Start > Settings > Control Panel > Administrative Tools
> Add/Remove Programs
).
Step 2
Remove Scalar DLC software from Node 1 (now the standard operation must work). Accept the
restart.
Step 3
Repeat Steps 1 - 2 for Node 2.
Note
This issue appears only for the Failover solution.
