Example: value=0=0x0 6-00020-02 Commands 113 SNC 5100 Usually a value of 0 indicates success, but some successful commands return a different value. arptabShow The arptabShow command displays the contents of the ARP table. The ARP table contains the current Internet-to-Ethernet address mappings. This information may be useful to the LAN administrator. SN60023 > arptabShow 192.168.1.19 at 8:0:20:23:2f:db value=0=0x0 SN60023 > cd You can move to a different directory (usually in the flash file system) using the cdcommand. SN60023 > cd "MGMT" value=0=0x0 SN60023 > clearReservation[devId] The clearReservation command can be used to force-clear a reservation held by a host for the specified target device. It may be necessary to issue this command if a host that has a reservation for a shared device was disconnected from the SNC 5100 without properly shutting down the application software that issued the reservation. If this is the case, other hosts that attempt to access the shared device will repeatedly receive reservation conflict status from the device. Issuing this command may result in resetting the target device. Parameter Value devId The index of the device (LUN) SN60023 > clearReservation 4 value=0=0x0 SN60023 > 114 Commands 6-00020-02 SNC 5100 The above example shows the clearReservation command being used to clear a reservation on a target device at LUN 4. cleHelp The cleHelp command displays a list of the Command Log Event facility commands. SN60023 > cleHelp CLE -Command Log Event facility cleShow -Displays Logged Events for a specific LUN cleShowAll -Displays Logged Events for All LUNs value=0=0x0 SN60023 > cleShow The cleShow command displays the last 64 Command Log events for a device at the specified LUN. The manufacturer may request the contents of the command log for diagnostic purposes. Information about interpreting these events is not provided. cleShowAll The cleShowAll command performs a cleShow for all LUNs. The manufacturer may request the contents of the command log for diagnostic purposes. Information about interpreting these events is not provided. csClearLogFile The csClearLogFile command clears the contents of the event log. SN600726 > csClearLogFile value=0=0x0 SN600726 > date The date command displays the system’s date and the time. The system may be set to read its local Real Time Clock (see the dateSetFromRTC command) or a remote host. See the rdate “timeserver” command. 6-00020-02 Commands 115 SNC 5100 The local Real Time Clock can also be synchronized with a remote timeserver See the rtcSetCurrent command. SN60023 > date SN60023 > THU JAN 25 20:32:49 2001 SN60023 > dateSetFromRTC The dateSetFromRTC command sets the SNC 5100’s RTC as the source of the date display. Use the date command to display the date and time. SN60023 > dateSetFromRTC value=0=0x0 SN60023 > diagBoot This command is used only to transition the SNC 5100 from normal operation to the special diagnostic mode. The diagBoot command first ensures that the ffs:mt directory exists. It verifies that the files diagnstk.o and diagnstk.rc are in the flash file system. If they are in the root directory, it moves them to the ffs:mt directory. It copies the existing bootline to a file in the ffs:mt directory on the SNC 5100 and installs a new bootline directing the SNC 5100 to boot using a special diagnostic startup script ffs:mt/diagnstk.rc. It renames the persistent map file config/device.map as config/device.bak (a new file will be generated after rebooting). Finally, diagBoot issues a reboot command to put the changes into effect Caution After completing use of the diagnostic commands, use the normalBoot command to restore your system to normal operation. diagHelp The diagHelp command displays a list of the diagnostic commands.

Specify one of two option parameters as follows. Option Number Value 1 Hides the Command and Control interface and results in Inquiry data returning “device not available” for LUN 0. 2 Completely disables all Command and Control functions The SNC 5100 is addressable as a SCSI target device for command and control support. On a Fibre Channel Interface, this device will be seen as logical unit number 0, (LUN 0). The LUN 0 device returns a device type of 0Ch in an inquiry command, indicating it is a controller device. Controller devices are defined in the SCSI-3 Controller Commands specification (SCC). In some cases, it may be desirable to disable this feature. If LUN 0 is disabled, then...
