110 Events and event messages
Description/Recommended actions
The controller that logs this event indicates which channel (path) has the problem. For example,
if the B controller logs the problem, the problem is in the chain of cables and expansion modules
connected to the B controller module.
Recommended actions:
● If this event is consistently logged for only one disk in an enclosure, perform the following
actions:
○ Replace the disk.
○ If that does not resolve the problem, the fault is probably in the enclosure midplane.
Replace the chassis FRU for the indicated enclosure.
● If this event is logged for more than one disk in an enclosure or disks in multiple enclosures,
perform the following actions:
○ Check for disconnected SAS cables in the bad path. If no cables are disconnected,
replace the cable connecting to the ingress port in the most-upstream enclosure with
reported failures. If that does not resolve the problem, replace other cables in the bad
path, one at a time until the problem is resolved.
○ If that does not resolve the problem, replace the expansion modules that are in the
bad path. Begin with the most-upstream module that is in an enclosure with reported
failures. If that does not resolve the problem, replace other expansion modules (and the
controller module) upstream of the affected enclosure(s), one at a time until the problem
is resolved.
○ If that does not resolve the problem, the fault is probably in the enclosure midplane.
Replace the chassis FRU of the most-upstream enclosure with reported failures. If that
does not resolve the problem and there is more than one enclosure with reported failures,
replace the chassis FRU of the other enclosures with reported failures until the problem is
resolved.
An unsupported disk type was found.
Recommended actions:
● Replace the disk with a supported type.
An unsupported disk vendor was found.
Recommended actions:
● Replace the disk with a disk that is supported by your system vendor.
The enclosure hardware is not compatible with the I/O module firmware.
The Expander Controller firmware detected an incompatibility with the midplane type. As a
preventive measure, disk access was disabled in the enclosure.
Recommended actions:
● If using a supported enclosure, update the storage system to the latest firmware. If using an
unsupported enclosure, replace the unsupported enclosure with a supported one.
The indicated SSD has 5% or less of its life remaining.
This event will be logged again as the device approaches and reaches its end of life.
Recommended actions:
● Be sure you have a spare SSD of the same type and capacity available.
● If a spare is available, replace the SSD now.
The indicated SSD has 20% or less of its life remaining.
This event will be logged again with a severity of Warning as the SSD further approaches its end
of life.
Recommended actions:
● Obtain a replacement SSD of the same type and capacity if you do not already have one
available.
