CommandDescription

fc rescan {/verbose} 

Scans connected SAN using FC adapters, discovers FC ports, storage controllers, logical units and then builds volatile FC database.

The "/verbose" qualifier enables FC communication trace on console (for diagnostic and troubleshooting).

fc show {adapter | port | device} 

Displays corresponding part of volatile FC database.

fc set {boot | dump} udid <X> 

Fills the environment variables wwid0..wwid3 and n1..n4 to identify path(s) to logical unit with the specified UDID.

These variables are later used by "INIT" to create device database entries and by OpenVMS/Tru64 to get access to boot and dump disks.

This command does NOT make any change to other environment variables.

fc set {boot | dump} wwid <X>

Fills the environment variables wwid0..wwid3 and n1..n4 to identify path(s) to logical unit with the specified WWID. 

These variables are later used by "INIT" to create device database entries and by OpenVMS/Tru64 to get access to boot and dump disks.

This command does NOT make any change to other environment variables.

This parameter is useful if UDID is absent.


Note

Only right part of the displayed WWID is used for specification, for example:
