Does SAN Connection Manager support dynamic disk functionality?

When I launch SAN Connection Manager, it takes a long time to open.

Symptoms:

None.

Solution:

None. This version of SAN Connection Manager does not support dynamic disk

functionality.

Symptoms:

This can be caused by a several factors:

The subsystem is busy servicing I/O. This only applies on first boot of the server

when the operating system is starting up, or when recovering from an error in the

caching service.

The Ethernet network is busier than normal with traffic.

There are many servers with HP HBAs and agents running. This requires more time

for these systems to respond and report to the SAN Connection Manager server

discovery.

There are many subsystems or the subsystems have many logical and physical disks.

This requires more time for the subsystems to gather and report the information to

SAN Connection Manager.

Solution:

Be patient. HP recommends launching SAN Connection Manager during periods of

light or no I/O traffic.
