146 Troubleshooting

When I open SAN Connection Manager, why doesn’t it discover my subsystems?

Why doesn’t SAN Connection Manager start up?

Why does the storage subsystem fail to create logical disk with maximum size?

Symptoms:

This can be caused by several factors:

Another application is running on the same or different system and connects to the

subsystem. Some storage subsystems only allow a single application to connect and

perform management functions on them.

The subsystems do not have an FC link to the SAN Connection Manager system.

SAN Connection Manager requires a direct FC link to discover and manage the

subsystem.

The subsystem’s hardware provider has not been installed or registered on the SAN

Connection Manager system.

Solution:

Ensure that your subsystems have a direct FC link and that the subsystem’s hardware is

registered on SAN Connection Manager.

Symptoms:

When I try to start SAN Connection Manager, it does not open and I get an error

message. This happens when multiple copies of SAN Connection Manager are trying

to be used within the SAN at the same time. On launching SAN Connection Manager,

a message box saying:

The application cannot run. No storage subsystem was

detected

.

Solution:

Close all instances of SAN Connection Manager running on other machines connected

to the SAN, and then re-launch SAN Connection Manager.

Symptoms:

When creating a logical disk with the maximum size allowed, some storage subsystems

fail the request with one of the following error messages:

Not enough space for the new logical disk.

Cannot complete the logical disk creation request.

This could be because the subsystems do not have enough space for the new logical

disk’s size. The subsystems might need space for the new logical disk overhead or

space is not available because of bad sectors on the drives.

Solution:

When this problem occurs, reduce the logical disk size and re-initiate the logical disk

creation request.
