RE: Cache Battery

Just had this done on our Power 720. I used our LAN console, but just because it's the closest terminal to the rack.

The tech used SST to fail the old batteries.
I shut the server down.
The tech replaced the batteries.
I hit the power button.
The tech used SST to close the fault for the old batteries.

I don't think anything specifically required a console.

Subject: Cache Battery

I am not going into all of the details, but we have a Model 520 ()Power 5) sitting in a remote site. I check it weekly for errors and accessibility (STRSST, and such).



There's a message that the cache battery needs to be changed. Actually that came up weeks ago, and they still have not changed it. But today the WRKDSKSTS panel (F11) showed all disks as "Degraded". I don't know what that means; the system is RAID5.



Anyway, they don't have a console there so they are telling me (supposedly from the IBM tech) that they have to set up a LAN console before they can change the battery.



Is that true? I mean, it's been years and I've been semi-retired for nearly
4 years, but my recollection is that the system has to be powered off, and powered back on. Do they really need a system console for this?
