MSA1000 locking up, slowly dying
The MSA on the left hand side, as seen from the front, is freezing up twice a week. The next time it stops, I'm thinking of taking the partner MSA, the one not 'backed' by the switch6 and substituting it for the troubled MSA on the left.
Will this work okay? Has the partner copied over the configuration of the drives?
----------------
In an MSA, which of the two controllers is normally considered the active, and which the backup? The one on the left or the one on the right, as seen from the front?
When I take an MSA1000 that's been sitting on the bench and plug it into the box, will whatever config was on it be overwritten by the config on the MSA1000 running in the box?

Re: MSA1000 locking up, slowly dying
I would assume that in either case the array configuration is available on both controllers - in both a/a and a/p.
As for overwriting the config I wouldn't think it would write over the config either, would be quite scary to do replacements then. Maybe it's more safe to do a ctrl replacement online then? Is that the advised way to replace the controller to do it online or offline?

Re: MSA1000 locking up, slowly dying
The array configuration is stored in RIS of the disks and not controllers.
If you are running A/P firmware, then controller on the right (when seen from front of the array) also called controller 1 will be active. Unless there was a controller failover.
Regarding plugging a controller in... it depends which slot you are plugging this into and if offfline/online and firmware version on it.
If you are plugging this into left slot (when seen from front) and right controller is active, then there should be no issues and firmwawre from right will be cloned to the left controller.

Re: MSA1000 locking up, slowly dying
4.32 is A/P version. The latest AP version is 5.40.
Take a look at the compatibility guide on HP.com, if you are planning to upgrade these.
