Upgrading firmware to 6.10 to 6.11 results in error, "RAID is not in optimal state on master node" (4226835)

Preparation

The appliance must be accessible via SSH (if it is not, configure it on the Basic Settings → Local Services page) as the fix needs to be copied to the box and this is the easiest way. You can also work via IPMI console if that's the only option - in such case you need some method to copy the fix over the network to the SPS. 

Check that the SPS in question is affected:
SSH into the SPS: ssh root@<ip_address_of_sps>

Select the Boot shell

Run the following command: xcbclient self xcb_get_lsi_raid_status 

If that command returns a multi-line error message, then the SPS is affected by this issue. If it returns "active" or some other one-line answer, then the SPS is not affected by this issue. 

Check that there's no ".local" directory in the root home (note the leading dot):
ls -l /root/.local 

Applying the fix

This fix was created specifically for this issue and only needs to be applied if it has been verified that the SPS appliance is affected. 

Download xcbdaemon-raid-fix.tar.gz.attached to the SR. This fix is compatible with both 6F10 and 6F11. 

Copy the tar.gz to the root home on the SPS: scp xcbdaemon-raid-fix.tar.gz root@<ip_address_of_the_sps> 

SSH into the SPS: ssh root@<ip_address_of_sps> 

Select the Boot shell 

Untar the package: tar xzf xcbdaemon-raid-fix.tar.gz 

Restart xcbdaemon service: systemctl restart xcbdaemon.service 

If the SPS is configured in High availability (HA), the above steps needs to be done on the slave (passive) node also. 

In order to ssh into the other node, run ssh scb-other command on the master node. To copy the fix to the other node, use scp:
scp xcbdaemon-raid-fix.tar.gz scb-other 

Verify that the fix is properly applied 

Run the xcbclient self xcb_get_lsi_raid_status command on the given node (master or slave). It should report a one-line text: active 

Cleaning up the files

This is an important step to not leave anything behind. If you leave behind the fix, it will cause upgrade issues in the future.

After the upgrade completed, ssh to the SPS instance(s) using a boot shell and remove the ".local" dir in the root home:

    rm -rf /root/.local

After this upgrade directly to SPS version 6.11.1.
