VA7410 few disks only seen by one controller
I have two drives on a 2nd ds2405 that aren't being seen by controller one. The drives and controller are listed in a "good" state through armdsp -a. I have cycled the DS2405 individually as well as cycled the VA7410 it is attached to.
Next steps were going to be a reseat controller 1 then replace one of the drives.

Re: VA7410 few disks only seen by one controller
Go with the drives and monitor. You might want to perform a full diag capture and have it analyzed (armdiag -I(UC i) -if
Check the disk error logs for signs of possible issues and compare against the other disks.
#armlog -d JB2/D7

Re: VA7410 few disks only seen by one controller
I am going to swap controller boards C1<->C2 and see if the problems follow over to the 2nd controller. Hopefully they will. If that is the case I will swap the bad controller board.
Please see attached output for more information. I will run the diagnostics check once the rebuild is complete.

FWIW:
Link cards and midplanes can also manifest themselves as disk channel errors, but further analysis would be required. I only see the 2nd enclosure reporting disks issues in the attachement and not the entire chain.

Re: VA7410 few disks only seen by one controller
The events go back when the 2 ds2405 was added to the va7410 about a week ago. The controller reporting all the problems has never been stable.
The array is still in a rebuild state=0% which concerns me.
Thanks for your help thus far

Re: VA7410 few disks only seen by one controller
What we need to find out is the reason the rebuild is stalled (maybe not enough available disks?)
# armrbld -p
Check that all disks are present and included with armdsp -a.
Check all Controller/Disk/Enclosure LEDs and logs.

Use the armdiag or armlog to review the events prior to the first rebuild failure and go forward, check for any messages pertaining to rebuild failures and reasons.
