Hi,

You can rename the LUN using lun move command even when it is online:

sin*> lun show /vol/volt/lunt

        /vol/volt/lunt             117.7m (123379200)     (r/w, online)  <-------- lun is online

sin*> lun move /vol/volt/lunt /vol/volt/luntRenamed  <-------- lun move, same volume different name.

sin*> lun show /vol/volt/luntRenamed

        /vol/volt/luntRenamed      117.7m (123379200)     (r/w, online)  <-------- lun is online

Thanks,

Thanks for the reply Arun

Will it affect the data if it is done online? The LUN I intend to rename is used as an OS lun

Hi,

AFAIK data won't be affected but not sure whether the LUN mapping would be intact. you can do a test with normal LUN before you rename the OS LUN. Just rename a LUN that is mapped and verify the mapping is intact and the LUN is still accessible from OS. If yes, then you should be able to do the same on OS LUN.

Thanks,

Thanks Arun... when u say mapping.. do u mean the mapping of lun with igroup....?

PS: I will be renaming igroup as well

Regards,Rahul

[arunchak]

yes, I was meaning the mapping of lun with igroup, which would not change if you just rename the LUN, but its better to check the access from host side.

It won't affect data access from the host side.  No downtime.  It can also change the path within the volume or qtree as long as in the same volume.. you can lun move from /vol/volt/lun to /vol/volt/qtree/lun for example.
