Installation Troubleshooting; Problems With Initial Setup - IBM Storwize V7000 Unified Problem Determination Manual

If all nodes show either node error 550 or node error 578, you might need to
perform a system recovery. See "Recover system procedure" on page 257 for more
details.
For more information about determining and solving block storage problems that
relate to the control enclosure, see "Resolving a problem" on page 200.
Check the intrasystem connectivity by using the management GUI. Navigate to
Monitoring > System. Use the interactive graphic to determine the connection
state by hovering over each connection in the graphic.
If either of the Fibre Channel links from the file modules shows an error or
degraded state, see "Fibre Channel connectivity between file modules and control
enclosure" on page 34.
If mgmt0, the direct Ethernet link between the file modules, shows an error or
degraded state, see "Ethernet connectivity between file modules" on page 26.
If one or both of the Fibre Channel links from the file module to the control
enclosure show an error or a degraded state, see "Ethernet connectivity from file
modules to the control enclosure" on page 29.
Check the core component health. Navigate to Monitoring > System Details >
Interface Nodes > nodename > NAS Services. In the Status panel, check the CTDB
state and the GPFS state.
If the GPFS state is Active, but the CTDB state is not Active, see "Checking CTDB
health" on page 169; otherwise, see "Checking the GPFS file system mount on each
file module" on page 171.
If you have lost access to the files, but there is no sign that anything is wrong with
the Storwize V7000 Unified system, see "Host to file modules connectivity" on
page 25.
