Log in as root user.2. Enter the following command:lscfg -vp | grep alterable3. Press enter. A report will be produced similar to the following:ROM Level.(alterable).......sh000221 <=== service processor F/W levelROM Level.(alterable).......SPH00056 <=== system F/W levelNotes:1. In the example above, if the current version of service processor firmware issh000221, the last six characters of the ROM Level represent a date in a yymmddformat, where yy is the last two digits of the year, mm is the month and dd is the dayof the firmware (Julian date).2. Also in the example above, if the current version of system firmware is SPH00056,the last five characters of the ROM Level represent a date in a yyddd format, whereyy is the last two digits of the year and ddd is the Gregorian date of the firmware.Check the RS/6000 support web site at http://www.rs6000.ibm.com/support/micro for thelatest level of downloadable firmware.

The firmware update file must be written into the /tmp/fwupdate directory on theModel 270. This can be done by using the ftp command to get the image from anftp server, NFS-mounting the directory on the host server, or downloading it from theweb site at http://www.rs6000.ibm.com/support/micro.After the firmware update file has been written into the /tmp/fwupdate directory,verify its existence by entering the following command:287
