Hello Tkn2021,

 

I could recommend a few initial checks:  check Firmware and/or a loose connection. Reseat all cables and connections and update the firmware (controller, MDSM and hard drives).

 

Was the replacement drive listed on the support matrix?

Dell EMC PowerVault MD32XX/36XX Series Support Matrix

If those check out you can upload the support bundle here, then Private Message me the service tag so that I can retrieve the report.

Hello Tkn2021,

 

I received your private message. Thank you for the report.

I was out sick yesterday. I will get a look at the support bundle and update you a soon as I can.

Hello Tkn2021,

 

 

I have reviewed the log and outlined Plan Of Action:

 

• Suggestion to have a verified backup based on number of old failing drives
• Determine if 0:5, 0:19, 0:22 were physically replaced on 26th and 30th
• • If not physically replaced,
  • • Replace them safely
• Replace 0:10, 0.13
• Update HDDs

ST900MM0006, v.LS08 update to v.LS0C

ST900MM0036  v.LSF5 update to v.LSF7

ST900MM0006 v.LS06 update to LS0C

AL13SEB900 v. DE09 update to v. DE11

ST900MM0006 v.LS0B update to LS0C

• Correct network configuration
• • Currently
  • • Each controller is on a different subnet
    • Each host only connects to 1 controller
    • This means that access during failover is only through 1 host at a time
  • What it should have
  • • Each controller has 2 subnets
    • Each host should have multiple connections to each controller
• Verify best practices are setup on switches
• • https://dell.to/3qpi6y3
• Verify that MPIO on VMware is set to Round Robin
• Correct MTU size to match on all ports
• • Currently RC0P0 and RC0P1 are set to 9000 while all other ports are set to 1500
