MSA 2062 secondary controller not connected

lex4hex — Tue, 06 Apr 2021 11:04:43 GMT

Dear Community,

I'm quite new on MSA installation and I have the following issue:

I have 2 Host (vsphere) HPE DL 380Gen 9 with H241 HBA

2 Mini SAS cables each host connected in this way:

Host 1 Sas 1 > MSA Crt A DP1

Host 1 Sas 2 > MSA Crt B DP1

Host 2 Sas 1 > MSA Crt A DP3

Host 2 Sas 2 > MSA Crt B DP3

My problem is that Controller B has no link. Only Controllr A is apparently connected and on the MSA management page cable connected to Crt A show initiator discovered and cable on Crt B show not discovered,

On this way resterting Crt A I no failover reaction loosing the connection to the datastores.

Any help would be really appreciated

Thanks

As this is new setup so you can shutdown the system and keep Controller A down or remove it. Then try using SAS cables which you have used for Controller A, use them for Controller B connectivity and see if this is cable issue.

Next swap controller position and then verify if this is Controller issue.

Hope this helps!

Should work.
In addition to Subhajit, cross-change the SAS Cables and Ports.
Sometimes the SAS did not fully Plug-In.

Connect with SSH (Putty) and use these commands to check for MSA problems:

show system
show controllers
show host-parameter
show ports detail

Post Output and we can check.
