Operating Systems AIX How can I manage redundant HMC upgrades with firmware upgrades? Post 302346923 by balaji_prk on Monday 24th of August 2009 11:59:07 AM

How can I manage redundant HMC upgrades with firmware upgrades?

Lets says I have 2 HMC's A and B, connected to a p570 managed system.

Right now the firmware level of the p570 is EM320_076 and that needs to be upgraded to EM340_095.

Now the HMC's are at V7R3.3 and as per the code matrix the HMC's needs to be upgraded to V7R3.4 Servicepack 2.

Now my query

1. Should I be upgrading both HMC A & B before upgrading the firmware of p570.

2. If I leave one HMC as it is and upgrade the other one only and then upgrade the firmware level on p570, will there be any issue?

let me know if I not clear.

Balaji

NAME
splitdns323fw - extract data from DNS-323 (and other) firmware images SYNOPSIS
splitdns323fw [-k KERNEL] [-i INITRD] [-d DEFAULTS] firmwarefile DESCRIPTION
splitdns323fw parses an existing firmware image for a device such as the D-Link DNS-323, DNS-321, and Conceptronics CH3SNAS. By default, if only the firmwarefile (R)option is given, the script verifies the checksums of the included components and prints a bunch of useful info about the image. If you specify one or more of the other options, however, the corresponding section of the firmware image will be written to that file. -k kernel, --kernel=kernel Write the kernel part of the firmware image to the specified file. -i initrd, --initrd=initrd Write the initrd part of the firmware image to the specified file. -d defaults.tar.gz, --defaults=defaults.tar.gz Write the defaults part of the firmware image to the specified file. BUGS
E-mail bug reports to theshed+dns323-firmware-tools@hezmatt.org. I don't guarantee to be able to help, but I'll give it a shot. Patches are far more helpful. AUTHOR
