disk.lun.allMemoryAvailable

Severity

NOTICE

Description

This message occurs to confirm that enough memory is present to successfully allocate command blocks for all of the disks in the system and for additional LUNS.

Corrective Action

(None).

Syslog Message

disk_init :Allocated all memory required for array LUNs.

Parameters

(None).

disk.lun.outOfMemory

Severity

NOTICE

Description

This message occurs when the system cannot allocate the additional memory for LUNs.

Corrective Action

(None).

Syslog Message

disk_init: Unable to allocate memory for array LUN commands on %s.

Parameters

diskName (STRING): Name of the device that could not allocate memory.

disk.lun.sizeTooLarge

Severity

ALERT

Description

This message occurs when an array LUN on an external RAID storage subsystem or a virtual disk is too large to be used as storage by the controller.

Corrective Action

Reduce this array LUN size, or re-create the virtual disk within the parameter limit.

Syslog Message

Array LUN or virtual disk %s is too large (%s bytes) and cannot be used. The maximum permissible array LUN or virtual disk size is %s. Reduce this array LUN size by %lld bytes, or re-create the virtual disk within the parameter limit (%lld %d byte blocks).

Parameters

diskName (STRING): Name of the array LUN or virtual disk that is too large.
lunSize (STRING): Size, expressed in bytes, of the array LUN or virtual disk that is too large.
maxSize (STRING): Maximum permissible array LUN or virtual disk size, expressed in bytes.
byteDiff (LONGINT): Difference, expressed in bytes, between the array LUN or virtual disk size and the maximum size Data ONTAP® supports.
blockDiff (LONGINT): Difference, expressed in blocks, between the array LUN or virtual disk size and the maximum size Data ONTAP supports.
blockSize (INT): Block size of the array LUN or virtual disk.

disk.lun.sizeTooSmall

Severity

ALERT

Description

This message occurs when an array LUN on an external RAID storage subsystem or a virtual disk is too small to be used as storage by the controller.

Corrective Action

Delete the array LUN or virtual disk and re-create it within the parameter limit.

Syslog Message

LUN or virtual disk %s is too small (%s bytes) and cannot be used. The minimum permissible LUN or virtual disk size is %s. Increase this LUN or virtual disk size by %lld bytes (%lld %d byte blocks).

Parameters

diskName (STRING): Name of the LUN or virtual disk that is too small.
lunSize (STRING): Size, in bytes, of the LUN or virtual disk that is too small.
minSize (STRING): Minimum permissible LUN or virtual disk size, expressed in bytes.
byteDiff (LONGINT): Difference, in bytes, between the LUN or virtual disk size and the minimum size Data ONTAP® supports.
blockDiff (LONGINT): Difference, in blocks, between the LUN or virtual disk size and the minimum size Data ONTAP supports.
blockSize (INT): Block size of the LUN or virtual disk.

disk.lun.unsupportedBlkSize

Severity

ALERT

Description

This message occurs when an array logical unit (LUN) on the external RAID storage subsystem reports an unsupported block size.

Corrective Action

Reformat the array LUN with a supported block size.

Syslog Message

disk_init: Array LUN %s reports a block size of %u bytes and it cannot be used. Reformat the array LUN with a supported block size.

Parameters

diskName (STRING): Name of the array LUN with the unsupported block size.
sector_size (INT): Unsupported block size.
