Hello, Shawn,

You are right it is Enhanced Concurrent VG I want to create it on HDS9570v.
But when I create it I got the following error.

---------------------------------------------------------------------------------------------------------------------
Command: failed stdout: yes stderr: no

Before command completion, additional instructions may appear below.

0516-1254 mkvg: Changing the PVID in the ODM.
0516-1335 mkvg: This system does not support enhanced concurrent capable
         volume groups.
---------------------------------------------------------------------------------------------------------------------

You know from IBM Docs. I could not find any more information regarding HDS
disk on HACMP. I don't know whether there is any resource regarding this or
anyone has done this before.

Thanks for your kindly help.

rgd,

James Guo
