install module bios
To program the supervisor or switching module BIOS, use the install module bios system command.
install module module-number bios {system [bootflash: | slot0: | volatile: | system-image]}
Syntax Description
Defaults
None.
Command Modes
EXEC mode.
Command History
This command was introduced in Cisco MDS SAN-OS Release 1.0(3).
Usage Guidelines
If the BIOS is upgraded, you need to reboot to make the new BIOS effective. You can schedule the reboot at a convenient time so traffic will not be impacted.
The console baud rate automatically reverts to the default rate (9600) after any BIOS upgrade.
The URL is always the system image URL in the supervisor module, and points to the bootflash: or slot0: directories.
Examples
The following example shows how to perform a non disruptive upgrade for the system.
switch# install module 1 biosStarted bios programming .... please wait###BIOS upgrade succeeded for module 1In this example, the switching module in slot 1 was updated.
install module image
To program the supervisor or switching module image, use the install module image command.
install module module-number image kickstart [bootflash: | slot0: | volatile: | system-image]
Syntax Description
Defaults
None.
Command Modes
EXEC mode.
Command History
This command was introduced in Cisco MDS SAN-OS Release 1.0(3).
Usage Guidelines
The install module command only upgrades the system image on any module (other than the standby supervisor module). If error occur for any switching module, the module is reset and the new image is downloaded for that module.
If you are issuing this command on the supervisor module, follow these requirements:
•
Update the environment variables before issuing this command.
•
•
Examples
The following example shows how to perform a non disruptive upgrade for the system.
switch# install module 5 image system bootflash:system.imgBeginning the install check...bootflash:/system.img and kickstart image...is compatible.bootflash:/system.img image...can be upgraded non-disruptively from current.Preliminary install check done.Beginning the install process.Parsing of versioning database successful.Preparing file system plan now...Done.Preparing upgrade group plan now...Done.Executing pre-uninstall scripts...Done.Updating the File System for installation...Done.Executing post-install scripts...Done.System Manager will restart the services according to upgrade plan..Done.Installation completed successfully.Related Commands

install module loader
To upgrade the bootloader on either the active or standby supervisor module, use the install module loader command. This command is only for supervisor modules, not switching modules.
install module module-number loader kickstart [bootflash: | slot0: | volatile: | kickstart-image]
Syntax Description
Defaults
None.
Command Modes
EXEC mode.
Command History
This command was introduced in Cisco MDS SAN-OS Release 1.0(3).
Usage Guidelines
Before issuing the install module loader command, be sure to read the release notes to verify compatibility issues between the boot loader and the kickstart or system images.
If you install a loader version that is the same as the currently-installed version, the loader will not be upgraded. When both the current version and the installed version are the same, use the init system command to force a loader upgrade.
Examples
The following example shows how to perform a non disruptive upgrade for the system.
switch# install module 6 loader bootflash:kickstart_imageThis example displays the command being issued on the standby supervisor module in slot 6.

This command was introduced in Cisco MDS SAN-OS Release 1.1(1).
Usage Guidelines
This command is used to configure a static iSCSI target for access by iSCSI initiators. A virtual target may contain a subset of LUs of an FC target or one whole FC target.
Don't specify the LUN if you wish to map the whole Fibre Channel target to an iSCSI target. All Fibre Channel LUN targets are exposed to iSCSI.
One iSCSI target cannot contain more than one Fibre Channel target.
Examples
switch## config tswitch(config)# iscsi virtual-target name abc123switch(config-(iscsi-tgt))# ?ISCSI Virt-tgt Configuration:advertise Advertise virtual target on interfaces specifiedexit Exit from this submodeinitiator Allow iSCSI initiator access to this targetno Negate a command or set its defaultspWWN Enter the pWWN of the fc-targetThe following command advertises the virtual target only on the specified interface. By default, it is advertised on all interfaces in all IPS modules
switch(config-(iscsi-tgt))# advertise interface gigabitethernet 4/1The following command maps a virtual target node to a Fibre Channel target.
switch(config-(iscsi-tgt))# pWWN 26:00:01:02:03:04:05:06The following command enters the secondary pWWN for the virtual target node.
switch(config-(iscsi-tgt))# pWWN 26:00:01:02:03:04:05:06 secondary-pwwn 66:00:01:02:03:04:05:02Use the LUN option to map different Fibre Channel LUNs to different iSCSI virtual targets. If you have already mapped the whole Fibre Channel target, you will not be able to use this option.
switch(config-(iscsi-tgt))# pWWN 26:00:01:02:03:04:05:06 fc-lun 0 iscsi-lun 0The following command allows the specified iSCSI initiator node to access this virtual target. You can issue this command multiple times to allow multiple initiators.
switch(config-(iscsi-tgt))# initiator iqn.1987-02.com.cisco.initiator1 permitThe following command prevents the specified initiator node from accessing virtual targets.
switch(config-(iscsi-tgt))# no initiator iqn.1987-02.com.cisco.initiator1 permitThe following command allows the specified IP address to access this virtual target:
switch(config-(iscsi-tgt))# initiator ip address 10.50.1.1 permitThe following command prevents the specified IP address from accessing virtual targets:
switch(config-(iscsi-tgt))# no initiator ip address 10.50.1.1 permitThe following command allows all initiators in this subnetwork to access this virtual target:
switch(config-(iscsi-tgt))# initiator ip address 10.50.0.0 255.255.255.0 permitThe following command prevents all initiators in this subnetwork from accessing virtual targets:
switch(config-(iscsi-tgt))# no initiator ip address 10.50.0.0 255.255.255.0 permitThe following command allows all initiator nodes to access this virtual target.
switch(config-(iscsi-tgt))# all-initiator-permitThe following command prevents any initiator node from accessing virtual targets.
switch(config-(iscsi-tgt))# no all-initiator-permitRelated Commands
