If all nodes show either node error 550 or node error 578, you might need to
perform a system recovery. See āRecover system procedureā on page 380 for more
details.
For more information about determining and solving block storage problems that
relate to the control enclosure, see āResolving a problemā on page 236.
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 āFibre Channel connectivity between file modules and control
enclosureā on page 72.
If mgmt0, the direct Ethernet link between the file modules, shows an error or
degraded state, see āEthernet connectivity between file modulesā on page 65.
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 āEthernet connectivity from file
modules to the control enclosureā on page 68.
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 āChecking CTDB
healthā on page 187; otherwise, see āChecking the GPFS file system mount on each
file moduleā on page 189.
If you have lost access to the files, but there is no sign that anything is wrong with
the Storwize V7000 Unified system, see āHost to file modules connectivityā on
page 63.
