Parameters
Controller ID, Chip
ID
Message
Reset host i/f chip x in controller y
Description
The controller y resets chip x that failed to execute commands properly. This could be to recover
from transient error due to a unstable channel or heavy traffic. The controller will resume normal
operations of the chip after reset; however, this could result in performance drop of the LUNs
exported to the host ports of this chip.
Advice
If this event occurs often, check the host connectivity, or contact local sales or support office.

Message
Task abort on host port x from host y to LUN z
Description
The controller received task abort on host port x from host y to LUN z. This could be to recover
from a transient error due to unstable channel, command time-out, or unexpected host behaviors.
The controller will drop the command specified by the host, and the host will retry the command;
however, this could result in LUN performance drop.
Advice
If this event occurs often, check the host connectivity, check LUN’s IO statistics to see if the maxi-
mum response time is reasonable for the hosts connected, or contact local sales or support office.
