We have multiple systems using LSILogic PERC4 cards (PERC4e/Si,
PERC4/DC, amr driver). After recently upgrading two of them from 6.3 to
7.1, we have begun to see the following errors in our logs during heavy
use in both systems:
amr0: Too many retries on command 0xffffffff80a4da58. Controller is
likely dead
amr0: Too many retries on command 0xffffffff80a4eaa8. Controller is
likely dead
amr0: Too many retries on command 0xffffffff80a497a0. Controller is
likely dead
amr0: Too many retries on command 0xffffffff80a4eaa8. Controller is
likely dead
However, the system continues working and the volumes remain
accessible. This happens on the PERC4/DC controllers in both systems.
Firmware version is 352D. MegaCLI reports no problems.
Has anyone else seen these messages? A google search turns up nothing
but results in the driver code. Is this something we should be worried
about? We won't be moving any other systems to 7.1 until we can clear
this up.
The fix for this that I was thinking of is already in 7.1. There might
still be a driver bug, but I'm leaning more towards the controller
simply being busy. Do you have a reproducible test case that I could
try?
