zflash
NAME
zflash − Loads images into the flash ROMs on the OpenArchitect switch.
SYNOPSIS
zflash -d <dev> [-o|-O <offset>] <image_file>
<upgradeipmi.img>
DESCRIPTION
zflash enables you to program the flash ROMs on the switch. The switch contains 3 flash
ROM devices: the boot ROM flash, application flash 1 and application flash 2. Care should be
taken when flashing new images into the switch. Incorrect procedures can result in a switch that
cannot boot; especially when flashing the boot ROM referred to as device 0. See Switch
Maintenance for updating the flash ROM images.
OPTIONS
-d <dev> Specifies the ROM device being programmed. Dev must be
a number 0, 1, or 2 corresponding to the boot ROM, application
flash 1, or application flash 2 respectively.
-i <upgradeipmi.img> will load the file <upgradeipmi.img> into
the IPMI controller flash memory. This updates the program
version, it does not affect the FRU data.
Progress indicators will be printed during the update. It may
take four minutes to flash.
Once the update is complete, the IPMI controller is rebooted,
which may cause the shelf manager to temporarily disable
fabric ports until the reboot is complete.
EXAMPLES
The following example loads a new initial RAM image into application flash 1 at the default
offset of 0:
zflash -d 1 rdr6000.zImage.initrd
The following example loads a new boot image into the boot ROM at the default offset of 0:
zflash -d 0 zx6000.img
