Event ID 0x300f
Type HOST Severity WARNING Parameters
Host Port ID,
Host WWPN,
LUN ID
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 maximum response time is reason-
able for the hosts connected, or contact local sales or support
office.
Event ID 0x3010
Type HOST Severity INFO Parameters Host Port ID

can be started.
Advice None
Event ID 0x3011
Type HOST Severity WARNING 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 nor-
mal 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.
