RF (Reliability Factor)

The RF (Reliability Factor) command displays the current reliability factor for peripheral units and paths. For Fibre Channels, fibre interface statistics are included following the RF display.

Explanation

RF <device type> <unit number list>

Displays the reliability factor of the devices in the unit number list.

RF CHANNEL <device number>

RF CHAN <device number>

Displays the reliability factor for a channel.

RF TAP <tap number> MT <unit number>

RF TAP <tap number> STORAGESYSTEM <unit number>

RF TAP <tap number> STOR <unit number>

Displays the reliability factor for a TAP.

TAPs are Fibre Channel ports on Fibre Channel disk units, tape units, and storage systems. RF TAP shows usage of the subject Fibre Channel port by the MCP system where the command is entered. RF TAP does not reflect the simultaneous use of the subject Fibre Channel port by other MCP systems or by non-MCP systems.

RF FC

Displays the reliability factor for all Fibre Channel channels.

RF TRANSCEIVER CHANNEL <fc channel number>

RF TRANSCEIVER CHAN <fc channel number>

RF TRANS CHANNEL <fc channel number>

RF TRANS CHAN <fc channel number>

Displays the transceiver data from the specified Fibre Channel channels.

RF TRANS FC

Displays the transceiver data from all Fibre Channel channels.

Considerations for Use

For MT units, you can clear the reliability factor percentage by using the RW (Rewind) command. Otherwise, use the UR (Unit Reserved) command. You can also clear the reliability factor percentage by Halt/loading the system. Clearing the RF percentage does not clear fibre interface statistics for a Channel. The cell containing the FC HBAs must be power-cycled to clear these statistics.
