Prism FC420 Services Software Commands

25

ServicesLUN

Identifies the LUNs (one per Fibre port) 

to be used during an in-band command 

line interface (CLI) session with a given 

host. This information is taken from 

NVRAM.
Any map coinciding with a user-

specified ServicesLUN must first be set 

to offline before attempting to change 

the ServicesLUN. This map will be 

destroyed upon power-cycling the 

FC420 bridge. Disabling a ServicesLUN 

for a particular Fibre port will destroy 

the map to the FC420 bridge for that 

port.

set serviceslun [fp] [[fl] | 
disabled]

get serviceslun <[fp]>

SpeedWrite

Enables/disables SpeedWrite 

functionality to any SCSI device 

currently mapped to the FC420 bridge. 

To enable/disable SpeedWrite for a 

particular device, specify the SCSI bus 

(sb), the target (st), and the LUN (sl). 

Specify “all” to enable/disable this 

option for all currently mapped SCSI 

devices.

set speedwrite [sb st sl | all] 
[enabled | disabled]

get speedwrite [sb st sl | all]

SpeedWriteDefault

Enables/disables SpeedWrite 

functionality as a default condition 

when SCSI devices are mapped to the 

FC420 bridge.

disabled

set speedwritedefault [enabled 
| disabled]

get speedwritedefault

Temperature

Reports the unit temperature in 
degrees C.

get temperature

VerboseMode

Sets the Command Line Interface to 

display extended information about a 

parameter when the 

help

 command is 

given. When verbose mode is enabled, 

parameter values are generally 

preceded by labels in responses to the 

get

 commands. Only the parameter 

value is output when verbose mode is 

disabled. 

enabled

set verbose [enabled | 
disabled]

get verbose

VirtualDriveResponse

Enables/disables the virtual drive 

response feature, which allows the 

FC420 bridge to provide proxy 

responses to SCSI INQUIRY and TEST 

UNIT READY commands in the event of 

a SCSI device selection time-out or busy 

event.

disabled

set virtualdriveresponse
