Node in switched cluster not serving data after power maintenance

Last Updated:

Applies to

  • Cluster interconnect switches


  • After scheduled power maintenance, nodes are powered up but one or more nodes do not serve data.
  • Aggregates on non-working nodes report state unknown in storage aggregate show:

Aggregate     Size Available Used% State   #Vols  Nodes            RAID Status
--------- -------- --------- ----- ------- ------ ---------------- ------------
root_n1          -         -     - unknown      - cluster1-01      -
aggr_n1          -         -     - unknown      - cluster1-01      -
root_n2     3.04GB   152.4MB   95% online       1 cluster1-02      raid_dp,
aggr_n2    31.77GB   31.75GB    0% online       1 cluster1-02      raid_dp,

  • Cluster ports are link down in network port show:

                                                  Speed(Mbps) Health   Health
Port      IPspace      Broadcast Domain Link MTU  Admin/Oper  Status   Status
--------- ------------ ---------------- ---- ---- ----------- -------- ------
e0a       Cluster      Cluster          down 9000  auto/-     -        false
e0b       Cluster      Cluster          down 9000  auto/-     -        false

  • Output of storage failover show indicates nodes are waiting for cluster applications to come online:

Node           Partner        Possible State Description
-------------- -------------- -------- -------------------------------------
cluster1-01    cluster1-02    true     Connected to cluster1-02
cluster1-02    cluster1-01    true     Connected to cluster1-01.
                                       Waiting for cluster applications to
                                       come online on the local node.
                                       Offline applications: vldb, vifmgr,
                                       bcomd, crs, scsi blade, clam.

  • First node to come up will typically be cluster master and serving data, whereas other nodes are powered up but cluster apps are offline and not serving data.
