3par 7400 does not initialise chunklets
Posted: Mon Oct 10, 2022 10:49 am
Hey everybody
I have a strange problem with 3par 7400 2-node system
I had to replace a node on it and wanted to start from scratch so I performed deinstallation
So now it is not able to perform OOTB fully, specifically it does not create admin volume
It sees both nodes, the cage and cabling tests are passing, it sees my 4 disks
admitpd admits them and it says all 4 are valid
but next it is supposed to start chunklets initialization and this does not happen
it can wait forever saying that 20 chunklets for admin volume are not clean yet
showpd -c then says all chunklets are uninitialized
OOTB stress test log also shows that no chunklets are initialized during initialization stage
I see no events regarding this
just see that cage is constantly changing its state
showpdch -cng says all chunklets have to be cleaned but nothing happens, the system cleans nothing
Does anybody know where to dig next or how to trigger chunklets initialization manually?
