One cluster is offline

[obsidian wren]

Is there any way of fixing this kind of problem?

Do you know why node2 was taken over? If you fix whatever issue was happening on node2, then you can do a "storage failover giveback -ofnode cluster01-02" to give the control of node2 back.

Once the giveback is complete, you can do a "net int revert *" to send all the LIFs back to their home node.

[obsidian wren]

I have no idea why it was taken over, is there any way to diagnose it?

[odd delta]

Connect via SSH to the SP of node2 and check in what condition it is.

system power status
system console

Check if the system is in the Loader.

If the cluster has support, simply call and let them handle it.
But according to the screenshot it looks like the version is quite old...

[obsidian wren]

It shows that node2 has RPC: Port mapper failure - RPC: Timed out

[obsidian wren]

I've contacted support and they say that there is possibilty of physical failure of controller of this node.

[limpid flax]

"event log show" is probably the best place to start.

[barren aspen]

this is the usual error. you need to check the console/SP/BMC of the second node as OG1 wrote

you probably just need to boot the second node and everything will fix itself after a few minutes 😄

[obsidian wren]

If I try to reboot it shows the rpc port mapper failure

sadly

[obsidian wren]

It is unable to list entries on node-2 because of port mapper failure

It truly may be physically broken

[twin fjord]

What is the status when you physically connect to console port of bad system OR SP and access console?

SP-NODE> system console

Is the node sitting at LOADER-B> ?

[barren aspen]

please look in the SP/BMC not in the cluster, as people suggested multiple times

[obsidian wren]

yes it is sitting on loader b

[twin fjord]

Try

boot_ontap

[obsidian wren]

that's what I see after boot_ontap, do You reckon any of this errors?

[twin fjord]

Possibly bad DIMM

DIMM-NV1

[obsidian wren]

I will try replacing it

[odd delta]

ONTAP 8.2.3P5 Cluster-Mode

[barren aspen]

yeah, that DIMM is toast

also duplicate shelf IDs

[obsidian wren]

yeah I know 😅

[obsidian wren]

yeah so that is fixed and now I'm waiting for new ram delivery
