Issue

  • After motherboard replacement, the CFO giveback was successful but SFO giveback failed due to cluster port not being online. Hence halted the node and re-introduced original Motherboard into the system to troubleshoot cluster port issue.
  • Post booting the node and issuing a CFO giveback, the surviving HA partner rebooted due to a multi-disk failure experienced on it

       PANIC: raid: Unable to find root aggregate. Reason: Unknown. (DS=55, DL=8, DA=8, BDTOC=0, BDLBL=0, BLMAG=2 BLCRC=0,
BLVER=0, BLSZ=0, BLTOC=0, BLOBJ=0) in SK process rc on release 9.12.1P10 (C) on Sun Mar 10 11:09:05 GMT 2024

  • The node reboots and comes back normally but the reboot will lead to a temporary outage
