Actually it creates a 16/20mb partition caused by the access group. I'm using a Dell MD3000i. I have seen this on multiple MD3000i's with and without the firmware update 7.xxx
One article stated to simply go to "Host to virtual disk mapping" on MDSM and remove the one of the two "access" groups, but I get error:
"You cannot change or remove an Access virtual disk mapping. The Access virtual disk is required for hosts to access the storage array using in-band management"
Anyone know how to get rid of this dumb partition? I noticed sometimes this happens and sometimes it doesn't.
