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).

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.

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.

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.

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.
