T2000 firmware often ignored
By clive on May 28, 2008
Many customers(and engineers!) ignore firmware as part of their patching strategy and this can result in hard to diagnose issues. Over the last couple on weeks I have come across a couple of customer performance issues (some 1st hand and some 2nd hand) on T2000 which were resolved by applying the current firmware patch.
We have very limited observability in th firmware layer, so diagnosis can be a challange to say the least.
So in the spirit of avoiding future problems, have a quick look at the output of prtconf -V and if it does not show 4.28.1 or later, consider applying the patch 136927-01 or later if you are reading this in 6 months time. This is a patch where a long cool read of the README and install instructions is savy.
Same principle applies to T1000 and T5220's, but the patches are different.
