(None).

Syslog Message

Disk %s exceeds the average IO latency threshold and will be recommended for failure.

Parameters

disk_name (STRING): Name of the disk.

shm.threshold.lipStormReset

This message occurs when the system detects more than three media (recovered or medium) errors on the same block.

Corrective Action

(None).

Syslog Message

shm: Disk %s has had multiple media errors on sector %llu.

Parameters

diskName (STRING): Name of the disk.
block_num (LONGINT): Block number.

shm.threshold.mediaErrorsReassign

Severity

ERROR

Description

This message occurs when the system detects more than three medium and/or recovered errors in a 10-minute window on the same disk sector. The bad sector will be reassigned.

Corrective Action

(None).

Syslog Message

shm: Disk %s has had multiple media errors on the same sector in the last 10 minutes, and is reassigning the sector.

Parameters

diskName (STRING): Name of the disk.

shm.threshold.mediumErrors

Severity

ERROR

Description

This message occurs when the system detects more than 25 medium errors in a 10-minute window.

Corrective Action

(None).

Syslog Message

shm: Disk %s has crossed the medium error threshold in a 10 minute window.

Parameters

diskName (STRING): Name of the disk.

shm.threshold.mediumErrors7days

Severity

ERROR

Description

This message occurs when the system detects more than 100 medium errors in a seven-day window.

Corrective Action

(None).

Syslog Message

shm: Disk %s has crossed the medium error threshold in a seven-day window.

Parameters

diskName (STRING): Name of the disk.

shm.threshold.ratedLife

Severity

NOTICE

Description

This message occurs when the rated life used by a solid state drive (SSD) exceeds 90%. When an SSD reaches 100% of rated life, it might not be able to retain data while powered off for long periods of time.

Corrective Action

The number of weeks of rated life remaining indicated for each SSD is an estimate based on past usage. If the SSD is expected to remain in service beyond the estimated remaining time, initiate planning for SSD replacement when the rated life reaches 100%. Use the "storage disk show -ssd-wear" command to monitor the current rated life used by your SSDs.

Syslog Message

shm: There are %d drives that have consumed at least 90 percent of their rated life: %s.

Parameters

count (INT): Count of drives that have exceeded the threshold.
disk_names (STRING): Name, percentage of rated life and estimated remaining time before reaching 100% rated life of each SSD that has exceeded the threshold.

shm.threshold.ratedLife2

ERROR

Description

This message occurs when the rated life used by a solid state drive (SSD) exceeds 95%. When an SSD reaches 100% of rated life, it might not be able to retain data while powered off for long periods of time.

Corrective Action

The number of weeks of rated life remaining indicated for each SSD is an estimate based on past usage. If the SSD is expected to remain in service beyond the estimated remaining time, initiate planning for SSD replacement when the rated life reaches 100%. Use the "storage disk show -ssd-wear" command to monitor the current rated life used by your SSDs.

Syslog Message

shm: There are %d drives that have consumed at least 95 percent of their rated life: %s.
