Restrictions
•
You cannot define an LU path to journal volumes.
•
You cannot define an LU path to pool volumes.
•
When defining LU paths, you must not use RAID Manager and Remote Web Console at the
same time. If both programs are used simultaneously, operations may not be performed in
the expected order and the storage configuration might be defined incorrectly.
Guidelines
•
If you attempt to apply many settings in the LUN Manager windows, the SVP might be unable
to continue processing. Therefore, you should make nor more than approximately 1,000
settings. Note that many settings are likely to be made when defining alternate paths (see
“Defining alternate LU paths” (page 180)
), even though only two commands are required for
defining alternate paths.
•
Do not perform the following when host I/O is in progress and hosts are in reserved status
(mounted):
◦
Remove LU paths (see
“Deleting LU paths” (page 182)
)
◦
Disable LUN security on a port (see
“Disabling LUN security on a port” (page 186)
◦
Change the data transfer speed for Fibre channel ports
◦
Change AL-PAs or loop IDs
◦
Change settings of fabric switches
◦
Change the topology
◦
Change the host modes
◦
Remove host groups
◦
Setting command devices
Managing logical units workflow
1.
Configure fibre channel ports.
2.
Configure hosts.
3.
Configure LU paths.
4.
Enable LUN security.
5.
Set fibre channel authentication.
6.
Manage hosts.
Configuring hosts and fibre channel ports
When provisioning your system, configure hosts and fibre channel ports using LUN Manager. You
can manage hosts, modify the host configuration, and modify the port configuration when the
system is in operation.
