correct method for removing LUNs from Windows
On a Windows 2008 server, what is the correct method or removing power path LUNs? On MS MPIO, I just delete the partition, set the disk to offline, then get the storage engineer to remove the LUN from their side.
Is it okay to do this on power path multi pathing on Windows? Just wanted to make sure that removing the LUN/taking out all paths wont cause any issues.

Hello
To remove a LUN when PowerPath is present you can do the same - unmount ther volume,delete the partition and offline the disk. Then remove the disk from the host on the storage side. PowerPAth wqill report dead paths to that device - this is expected. Then opena command pormpt and issue the following command
powermt check
And answer a for All to remove the dead paths.
Note make sure the file powermt.custom or powermt.custom.xml is deleted from c:\program files\emc\powerpath or c:\program files\emc\powercommon (depending on version of PowerPath) before you do the powermt check.
