Interoperability Of Auto Lun And Raid Manager; Troubleshooting When Using Raid Manager - HP StorageWorks P9000 User Manual

Interoperability of Auto LUN and RAID Manager

When you perform a manual Auto LUN plan by using RAID Manager commands, note the following:
A volume reserved through Auto LUN cannot be used as a target volume.
A migration plan being executed by Auto LUN cannot be canceled using RAID Manager.
A migration plan created by Auto LUN cannot be displayed using RAID Manager.
Click File Refresh All on the menu bar of the Remote Web Console main window to check
RAID Manager settings in Remote Web Console.
While the microcode is being downgraded or upgraded, users must not perform any operations
that the resulting microcode would not support.
If you delete a manual Auto LUN plan, the volume status changes from SMPL(PD) to SMPL.
You can check the status of the volume by viewing the list at the bottom of the Manual Plan
window and confirming the existence of the manual migration plan.
You can check the status of a volume by using the pairdisplay command, but you cannot
distinguish between the SMPL and SMPL(PD) status.
When you delete a manual Auto LUN plan, you should wait until the status of the volume
changes from SMPL(PD) to SMPL (usually about 10 seconds) before executing another Auto
LUN operation through RAID Manager.
When you attempt to migrate a volume or cancel a migration plan through RAID Manager,
you might encounter an "EX_CMDRJE" exception and the command might be refused depending
on the condition in the DKC.

Troubleshooting when using RAID Manager

When you execute or cancel a manual Auto LUN plan through RAID Manager, you might identify
the cause of the error by referring to the log displayed on the RAID Manager window or in the
RAID Manager operation log file.
The RAID Manager operation log file is stored in:
/HORCM/log*/curlog/horcmlog_HOST/horcm.log
Where:
* is the instance number.
HOST is the host name.
The following figure shows an example of error log message in the RAID Manager window.
