XP120000 Upgrades - Which of These Activities Requires Downtime?
Firmware --- We're good. Systems can stay up.
Disks/Capacity Expansion - Ditto.
CHiP Blades - Ditto.
But what about:
- Cache Memory
- Shared Memory
- SM Platform Board
Do these require Downtime? Our FE and ASE Teams are a bit of different opinions.

Re: XP120000 Upgrades - Which of These Activities Requires Downtime?
Normally no downtime at all - maybe reduced performance due to cache related work.
What is the meaning of "SM Platform Board" ?
Add?
Hope this helps!

SM - Shared Memory Paltform Board.
So the XP can essentially stay Up and avialble right? Just dimished performance but of t will be a light day -- then who cares.
People pray a premium for these Tier-1 Hitachi based arrays to expect utmost up time - right?

Re: XP120000 Upgrades - Which of These Activities Requires Downtime?
If cache dims are replaced the whole of cache goes into maintainance mode which means cache-write pending is disabled for up to an hour. Any write intensive application will be severely impacted by this and so this could be considered a real outage.
Obviously mainly read apps will be less affected.
Changing Cache Dims should be considered HIGH impact...
