Symptoms

Oracle SuperCluster IO domains may fail to boot after upgrading to Solaris 11.3 SRU 11.6 or above (as part of Oracle SuperCluster latest QFSDP) due to BUG 22311453, if the system has already configured with more than 127 mac addresses per PF.

PDom console messages:

 If the allocated mac(alt-mac)-addresses count for a VF within the PF is more then 127, then the guest IO domain which uses the VFs from this PF will fail to boot.

Changes

 LDom v3.4 introduced in Solaris 11.3 SRU 11.6 puts a hard limit of 127 mac-address per PF.
