Cluster Recovery And States - IBM Storwize V7000 Troubleshooting And Maintenance Manual

Possible Cause-FRUs or other:
v None
801 Memory reduced.
Explanation: Memory is reduced but sufficient
memory exists to run I/O operations.
User response: Follow troubleshooting procedures to
fix the hardware.
803 One or more fibre-channel ports are not
operational.
Explanation: One or more fibre-channel ports are not
operational.
User response: Follow troubleshooting procedures to
fix the hardware.
805 One or more configured Ethernet ports
are not operational.
Explanation: None.
User response: Follow troubleshooting procedures to
fix the hardware.
815 Cannot determine the VPD for a
component.
Explanation: An FRU in the system has been changed,
and the VPD is unreadable or unrecognized.
User response:
1. Confirm that the correct parts were used in any
recent hardware replacement procedure.
2. Check whether a software upgrade is required for
the recently changed part. Follow the procedures to
upgrade the systems code version.

Cluster recovery and states

920 Unable to perform cluster recovery
because of a lack of cluster resources.
Explanation: The node is looking for a quorum of
resources which also require cluster recovery.
User response: Contact IBM technical support.
950 Special upgrade mode.
Explanation: Special upgrade mode.
User response: None.
990 Cluster recovery has failed.
Explanation: Cluster recovery has failed.
User response: Contact IBM technical support.
835 Unable to communicate with partner
node over PCIe link.
Explanation: The partner node is not in a state that
allows communication because the node is powered off,
a boot failure has occurred, or the PCIe link is broken.
User response: Follow troubleshooting procedures to
fix the hardware:
1. Determine status of other node.
2. Restart or replace the node if it has failed (should
be node error on partner)
860 The fibre-channel network fabric is too
large.
Explanation: This is a non-critical node error. The
node will continue to operate but only the first 1024
fibre-channel logins will be used. Connectivity
problems to the controllers, hosts, or other nodes could
exist.
User response: Fix the fibre-channel network
configuration:
1. View hardware WWNN information
2. Sort out the SAN
878 Attempting recovery after loss of state
data
Explanation: During startup, the node was unable to
read its state data. It expects to be added back into a
cluster, and reports this error while it is waiting.
User response: Allow time for recovery. No further
action is required.
