Description

Upgrade attempt fails with error 'must be run from primary'. 
 
'Error: This command only runs on the primary control server'.
 
Affects L2 HA pairs with Shared IP (VIP).


Scope
Version: 8.7.6,  8.8.2, potentially 8.8.1

Solution
Workaround:  Contact Support for assistance.

Solution: Addressed in versions 8.7.7, 8.8.3 and 9.1.

Workaround:  
    1) Login to CLI as root.
    2) Edit /bsc/campusMgr/bin/getIPAddr.

    Change.

        /sbin/ip addr show "$ETH" | sed -n 's/^\s\+inet \(.*\)\/.*/\1/p'

    To

        /sbin/ip addr show "$ETH" | sed -n 's/^\s\+inet \(.*\)\/.*/\1/p' | head -1

    3) Save changes.
    4) Repeat steps 1-3 for each appliance to be upgraded.
    5) Run the upgrade.
    6) Once upgrade is complete, review the getIPAddr script again. If the line has reverted back to:

        /sbin/ip addr show "$ETH" | sed -n 's/^\s\+inet \(.*\)\/.*/\1/p'

    Then modify the file as before (steps 2-3).  This will prevent the next upgrade from failing.
