Can someone from Netapp give me the run down on upgrading FC-AL shelves for clustering. I've heard conflicting information.
We have three FC-AL FC7 shelves that only have a single LRC card in them. I know that for clustering, the shelves will need an additional LRC card (for the second FC-AL loop).
It is not clear to me what is involved in adding the LRC card. I don't see this documented in the cluster conversion guide nor in the shelf hardware guide. I have heard that this is a field procedure that Netapp needs to perform and that after it is done, the shelves need to be calibrated. I heard the down time for all of this is supposed to be several hours.
The downtime is not a problem as we plan to move the disks from these shelves into a new set of FC7 shelves we are getting that will have two LRCs from the outset. I sent a message to toasters about this a few weeks ago.
I'd like to get an idea of exactly what is involved.
Thanks.

Jay, It is a simple process. You need to be on the latest firmware for the disks, system, etc.. Next simply power down the shelves and filer and take off the metal shield on the disk shelves where the second LRC card is to be installed. You will see a slot where the LRC cards seat into. Push the cards in and tighten down the screws. Only issue I would note on LRC cards is to make sure they are seated tight. Mike

I have had a LRC replaced in a cluster. The actual replacement was very quick. No calibration of any kind was performed after the replacement. I suspect installing secondary LRCs should be relatively quick nonevent.
