SAN failures might cause Lenovo Storage V7000 volumes to be inaccessible to host systems.
Failures can be caused by SAN configuration changes or by hardware
failures in SAN components.
The following list identifies some
of the hardware that might cause failures:
Power, fan, or cooling
Application-specific integrated circuits
Installed small form-factor pluggable (SFP) transceiver
Fiber-optic cables
If error codes sent you here,
complete the following steps:
Verify that the power is turned on to all switches and storage controllers that the Lenovo Storage V7000 system uses, and that they are not reporting
any hardware failures. If problems are found, resolve those problems
before you proceed further.
Verify that the Fibre Channel cables that connect the systems
to the switches are securely connected.
If you have a SAN management tool, use
that tool to view the SAN topology and isolate the failing component.
