Does Simple SAN Connection Manager support dynamic disk functionality?
When I launch Simple SAN Connection Manager, it takes a long time to open.
Symptoms: None.
Solution: None. This version of Simple 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 Simple 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
Simple SAN Connection Manager.
Solution: Be patient. HP recommends launching Simple SAN Connection Manager during
periods of light or no I/O traffic.
