upgrade weekend! – Part II

Update to http://rajeev.name/2006/06/30/upgrade-weekend/

FAS 960c is upgraded to FAS6070c. Some of the salient lessons learned
* We were planning on using the onboard FC tray for our disk shelf loops. Turns out that they come configured as targets, not as initiators. The fcadmin in the Disk Maintenance menu will allow one to change that setting and we were good to go once we did that.

* We first upgraded the 960s to ONTAP 7.2RC3 and then did the head swap. Voila! Coredumps on both filers… ouch! . We had to destroy the mailbox that was there (owned and operated by the 960s) and re-create it. That took care of that.

* After that, it was a simple disk unassign and assign job to migrate over the volumes…

1 cluster done – 1 more to go. This one’s gonna be tricky since I am going from FAS880 to FAs6070. First we are going to use the 960s from the previous cluster to “stage” the 880s to 960s. Then upgrade the 960s to 7.2 and then jump to 6070s.. sweet! (long night ahead)

I’ll post the stories on EMC and Ibrix later on ..
