"smpartition list active" Shows Inconsistent Partition Information Between Exalogic Switches

(Doc ID 1520330.1)

Last updated on APRIL 07, 2016

Applies to:

Oracle Exalogic Elastic Cloud Software - Version 2.0.0.0.0 and later
Exalogic Elastic Cloud X4-2 Eighth Rack - Version X4 to X4 [Release X4]
Linux x86-64
Oracle Solaris on x86-64 (64-bit)

Symptoms

You have an Exalogic system where information about nodes added to Subnet Manager partitions, which is expected to be identical across all the switches in the Exalogic rack (all NM2-GW gateway switches and any NM2-36P spine switch that is present within the rack configuration), appears to be inconsistent between some switches as the result of not being propagated across all the switches. As a result, information about changes to partitions is not present in all switches which could give rise to unexpected behavior in the event that one of the switches, whose partition list is incomplete/out of sync, assumes the role of the MASTER Subnet Manager (as identified by the "getmaster" command available on switches).

To determine whether or not the partition information is consistent across all switches, run the "smpartition list active" command and compare the output. As the output is long and since the output of the  "smpartition list active" cannot be easily redirected to a file (it pauses the output and requires the space/return key to be pressed in a "more" like fashion) the following script can be created as checkPartitionConsistency.sh and run:


In the case the partition information is already found to be consistent across each switch then no further action is needed from this note and further analysis of the problem will be necessary.
