Operating Systems AIX How can I manage redundant HMC upgrades with firmware upgrades? Post 302346998 by zxmaus on Monday 24th of August 2009 03:50:25 PM

Bala,

hmc firmware upgrades are downwards compatible but NOT upwards compatible. If you upgrade only one hmc and than the frame, you will have problems afterwards with the other hmc - if you upgrade both hmcs first, you won't have any issues and your not-upgraded frames won't have issues either.

Kind regards
zxmaus
