Thank you guyes for your help and replies and I apologize fot the delay as I was out of the office moving the shelves to another datacenter.
If my understanding is good, to get the DS14MK2-AT shelves attached to the FAS2240-2 I need a Mezzanine card in each one of the controllers. Once these cards are up I can then connect the DS14MK2-AT shelves following the guide. Does this operation require any specific configuration ? is it hot pluggable ? is it autoconfiguration ?
Also, I will not need to mix connection between DS14MK2-AT and DS2246 at anytime ? I was confused because DS2246 uses ACP cables and DS14MK2-AT does not.
Correct. You need to remove the existing mezz card which it seems is not in use, and replace it with the FC one. Then use fcadmin to ensure it is in initiator mode. Takeover and giveback one node at a time to install them.
I went into maintenance mode and test the newly installed hardware which was OK. I did not have to change the mezzaning fc ports from target mode to initiator mode as they were already configured so
C1NETAPP-VIRTU> ucadmin show Current Current Pending Pending Admin Adapter Mode Type Mode Type Status ------- ------- --------- ------- --------- ------- 1a fc initiator - - Online 1b fc initiator - - Online
Secondly, I set a unique ID for each of the 4 DS14mk2 shelves (4,5,6 and 7 in my case) and rebooted them. Then I used the below guide to connect the DS14mk2 FC Shelves to the mezzanine card (stack the disk shelves with the FAS224x system)
It's worth noting that these FC shelves were already used in production with another system. I was 100% sure that the stacking was correct but sysconfig -a or fcadmin device_map would not return me all the newly disks. I was able to detect this little issue by using a storage show which showed all disks and their respective owners, in the present case it showed that the old system still owning these FC disks. After that, I issued disk assign [DiskID] -s unowned -f on these disks, and the auto assign option took care to assign the newly 48 disks to my both nodes.
Aggregates and volumes creation went flawless.
I would like to thank you for all your availabiliy and assistance that you provided us with. Much apreciated. Regards, Radouane
