This issue mostly comes when we upgrade PSC ( appliances) , not able to open PSC in GUI mode.

 

This is certificate issue . there are 2 solution

1. Take snap shot and regenerate certificate then restart web-client service

2. Decommission affected PSC ( first check which PSC is pointing if you have 2 PSC) do not touch pointing PSC

3. Once Decomm delete it from disk and remove it from AD/DNS

4. Recreate DNS record

5. Deploy new PSC and join in Domain

6. Try IP/psc you should able to open it in GUI.

Mostly issue from storage side scsci reservation locked host's lock file and not able to release it

 

It depend on storage environment in vnx when we check we got

Here scsi reservation because of HLU and ALU was mismatch

Need to reconfigure from storage side and reboot all host in the cluster
