microcode upgrade

[tempest92]

could someone answer a couple of questions on microcode upgrades -

1) is there any way to backup your current system microcode before attempting an upgrade

2) is it OK just to upgrade system microcode even if the server has adapters that do not have their current level of microcode.

thanks.

1) no, unless you have the install file for the server's current microcode, there's no going back. You'll need IBM support if you run into problems (not likely to happen). Note that some systems enable you to back out an applied microdeode because they have two NVRAM sides. You apply the microcode to one side and try it out, if not satisfied, you use the other NVRAM side to boot.

2) yes, but you'll probably want to upgrade the adapters' microcode soon after the server anyway.


HTH,
