A Troubleshooting This appendix provides answers regarding the following: • Dynamic disk support-see page 139. • Launch-time support-see page 139. • Linux server on my local SAN is not discovered-see page 140. • Lost aliases support-see page 140. • New server support-see page 141. • OS support-see page 141. • Refresh Subsystem List support-see page 141. • Simple SAN Connection Manager does not discover my subsystems-see page 142. • Simple SAN Connection Manager does not start up-see page 142. • Storage subsystem fails to create logical disk with maximum size-see page 142. • Unknown Server is shown-see page 143. Does Simple SAN Connection Manager support dynamic disk functionality? Symptoms: None. Solution: None. This version of Simple SAN Connection Manager does not support dynamic disk functionality. When I launch Simple SAN Connection Manager, it takes a long time to open. 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. HP StorageWorks Simple SAN Connection Manager User Guide 139

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.
