Should be fine just adding P98 on top (node stability patches), P101 is only drive firmwares so not related to the main node patches.

We are on 3.3.1 Emu1. Not a big difference between reserved and used space.
Running the command , showeventlog -debug -oneline -msg GC -min 1440
--> I don't get much output except the system did not have any messages (-msg GC) to show .
I was lucky once t o see some of this messages (unclear what they ment) .
Since one must add -debug to the command, logging is restricted to go back a limited time.

So anybody an other idea to find out that the garbadge collector is still running execept making a HPE SR.

UPDATE

In case this can help anyone. Hp restarted the service remotely and have altered the frequency of the defrag on the cpg as the space reclaim wasn't catching up with the usual day to day data loss. This seems to have fixed the problem. In the past 2 hours we have reclaimed around 200Gb. If you have similar problems then this is what they need to do.

Bear in mind that our array is SSD and for spinning disk or heavily utilised system there may be a performance impact.

From putty "showspace -cpg cpgname" Then check the LDFree figure. This /1024 is the figure for Estimated maximum CPG size in the Capacity summary page from the web interface from the SSMC.
