MD3400 Degraded Physical Disk Channel

Hello Mittera IT,

When you get the Physical disk channel error what you want to do is to check to make sure all drives are online & present.  Are there any expansion enclosures attached to your MD3400?  Here are the commands that need to be run:

smcli -n -p password -c "clear allPhysicalDiskChannels stats;"

smcli -n -p password -c "set physicalDiskChannel [0] status=optimal;"

smcli -n -p password -c "set physicalDiskChannel [1] status=optimal;"

smcli -n -p password -c "set physicalDiskChannel [2] status=optimal;"

smcli -n -p password -c "set physicalDiskChannel [3] status=optimal;"

If after running the commands you are still getting the error then we will need to review a support bundle from your MD3400.  

Please let us know if you have any other questions.

I am looking and I don't see how to run these commands from the within the GUI.

Do I connect to the MD3400 via SSH, Telnet, another application?

Hello Mittera IT,

You will want to use SMCLI.  If you have MDSM installed on a host then you can just navigate to the folder and you will see SMCLI.

I ran into issues trying to connect via smcli with this error:
"Please check for any network problems and verify that there are fewer than the maximum allowed TCP connections"

However, within MDSM I did find the ability to "Execute Script" which I then tested the script and ran this:
clear allPhysicalDiskChannels stats;
set physicalDiskChannel [0] status=optimal;
set physicalDiskChannel [1] status=optimal;
set physicalDiskChannel [2] status=optimal;
set physicalDiskChannel [3] status=optimal;

The output is this:
Error setting physical disk channel status for physical disk channel "0" at line 2.
Error 223 - The operation cannot complete because there may be a problem with the physical disk channel itself, its associated cable may not be properly connected, or there are no expansion enclosures in this storage array.

The command at line 2 that caused the error is:

set physicalDiskChannel [0] status=optimal;

Error setting physical disk channel status for physical disk channel "3" at line 5.
Error 223 - The operation cannot complete because there may be a problem with the physical disk channel itself, its associated cable may not be properly connected, or there are no expansion enclosures in this storage array.

The command at line 5 that caused the error is:

set physicalDiskChannel [3] status=optimal;

Script execution complete.

All drives are online & present.
There is 1 expansion enclosure

Hello Mittera IT,

Can I get you to send me a support bundle?  I will send you a private message so you can send me the log.
