EVA8100 2C12D upgrade to 2C18D

[H S Z]

Hello Gurus,

i have a EVA8100 2C12D fully populated.
i have expanded it with a 0C6D according to the attached diagram. i did connect 1 top terminator in the main enclosure and 1 in the expansion rack.
after i connect all the expansion and the EAB numbers are all correct, i booted the 2 controllers together. they boot fully but shows on both controllers 0000.0000.0000.0000 as the WWN and no name for the EVA.
i then put the 2 controllers off, and boot controller A alone, it came up with correct WWN and EVA name and updated firmware of the enclosures. i then was able to access from the commandview and configured the disk groups. I'm still running with Controller A alone. when i boot Controller B, it still displays 0000.0000.0000.0000 as the WWN and no name for the EVA on it.
Has anyone faced this problem before?
appreciate your helps

I think we need to analyse the controller log files with help of HP Support team. Doesnt looks like a simple issue.

OK, next time read

HP StorageWorks EVA4x00-6x00-8x00 - M5314 drive enclosure installation instructions

You have disks in non-allowed bays.


Also, you may have some cabling wrong on the connections of the expansion cabinet.

Enclosures 15 - 17 go in loop 1.
Enclosures 18 - 20 go in loop 2.

hi, thanks for this doc. i have seen where my mistake is and if this does cause conflicts, its normal my storage behaves abnormally.
can i do this change online since this is production environment?

Only if you ungroup each disk before moving it. Pulling it while online and moving it to another place is not supported.

hello vcespon,
thanks for the great help.
i made the disks as it supposed to be, and the second controller came up.
