> invalid-cfmode-settings |  | invalid-cfmode-setting-info optional | Local and partner cfmode settings if they do not match. cfmodes need to match on both filers in the cluster or cluster failover will not work properly
> invalid-ostype-cfmode-settings |  | invalid-ostype-cfmode-setting-info[] optional | List of initiator groups with invalid ostypes for the fcp-cfmode. Some host operating systems are only compatible with certain fcp-cfmodes
> invalid-use-partner-cfmode-settings |  | invalid-use-partner-cfmode-setting-info[] optional | List of initiator groups with invalid use_partner settings for the FCP cluster failover mode (fcp-cfmode) Incorrect settings can cause hosts to lose luns during takeover.
> invalid-use-partner-ostype-settings |  | invalid-use-partner-ostype-setting-info[] optional | List of initiator groups with invalid use_partner settings for the initiator group's ostype. Some host operating systems should only have certain use_partner settings to ensure proper behavior during failover.

> Errno | Description
> EINTERNALERROR |  |
> EINVAL |  |

lun-config-check-info | [top]

> Returns a list of lun/fcp configuration warnings. These warnings are not related to filer cluster configuration.

> Output Name | Range | Type | Description
> alua-setting-mismatch-info |  | alua-setting-mismatch-initiator-group[] optional | list of initiator groups for which the ALUA (Asymmetric Logical Unit Access) settings do not match between local and partner filers. ALUA is a T10 standard that specifies the access characteristics (in terms of performance and supported SCSI commands) of a Logical Unit that can be accessed through more than one target port. ALUA is typically used by host multi-path software to recognize primary and secondary paths to a Logical Unit when more than one path are available to the Logical Unit. If the ALUA setting does not match between the local and partner filers, it would affect the host multi-path software's ability to distingush primary and secondary paths. This could lead to incorrect system behaviour.
> alua-setting-mismatch-initiators |  | alua-setting-mismatch-initiator-info[] optional | List of initiators which are members of initiator groups of differing alua settings.
> fcp-down-hbas |  | fcp-down-hba-info[] optional | list of HBA names that have no link or are configured down.

> mixed-vsa-initiators |  | mixed-vsa-initiator-info[] optional | List of initiators which are members of initiator groups with differing Volume Set Addressing (VSA) settings. An initiator can only be a member of initiator groups which have the same VSA setting across all the initiator groups it is a member of.

> Errno | Description
> EINTERNALERROR |  |
> EINVAL |  |

lun-config-check-single-image-info | [top]

> Returns a list of configuration warnings that pertain to problems specific to the 'single_image' fcp cfmode. These errors must befixed prior to upgrading any filer cluster to run in 'single_image' mode.

> Output Name | Range | Type | Description
> conflicting-initiators |  | conflicting-initiator-info[] optional | List of initiators which belong to initiator groups on the local filer which have different os type settings from the initiator groups on the partner.
> conflicting-maps |  | conflicting-map-info[] optional | Only one lun in the cluster can be mapped to an initiator at a given lun-id. If a lun on each filer is mapped to the same initiator at the same lun-id there will be a conflict. These conflicts need to be resolved before a filer can be upgraded to run in the 'single_image' fcp cfmode. A conflict can be resolved by unmapping one lun and remapping it to an unused lun-id.
> invalid-nodename-settings |  | invalid-nodename-setting-info optional | When running in the the single_image cfmode the fcp nodename needs to be same on each filer in the cluster. If the nodenames are different the nodenames will be returned. If the cfmode is not set to single_image, then the nodenames will not be checked

> EVDISK_ERROR_PARTNER_NOT_REACHABLE |  |

lun-config-check-wwpn-conflicts-info | [top]

> Determine if duplicate World Wide Port Names (WWPNs) are present on a cluster pair.

> Output Name | Range | Type | Description
> conflicting-wwpns |  | conflict-wwpn[] optional | If duplicate World Wide Port Names (WWPNs) are present on the HA pair, it leads to a conflict. This causes incorrect Asymmetric Logical Unit Access (ALUA) states to be advertised for all LUNs. To resolve the conflict use 'lun config set' command to set local.single_image.key and partner.single_image.key on both the nodes of the HA pair.

> Errno | Description
> EOPNOTSUPPORTED |  |
> EONTAPI_ENOMEM |  |

lun-create-by-size | [top]

> Create a new lun of given size, with initially zero contents. The lun is created at the path given. No file should already exist at the given path. The directory specified in the path must be a qtree root directory. The size of the created lun could be larger than the size specified, in order to get an integral number of cylinders while reporting the geometry using SAN protocols.

> Input Name | Range | Type | Description
> ostype |  | lun-os-type optional | The os type for the LUN. The default type if not specified is "image". It is strongly recommended for the caller of this API to avoid using the "image" type because it could result in misconfigured LUNs. For example, a lun with ostype "image" could suffer major performance penalties when a Windows host is trying to access it.
> path |  | string | Path of the LUN.
> prefix-size | [0..2^63-1] | integer optional | The size of the prefix stream for this lun in bytes. Certain OS types store a small portion of the data corresponding to partition tables (or similar structures) in the prefix stream. This is part of the lun data and is transparent to hosts that access the LUN via block protocols. The default size is based on the ostype. Giving a value here overrides the default, but, it is strongly recommended to avoid changing this default size. The value in this field must be a multiple of 512 bytes. Note that this value has no effect when the lun-os-type is "image". This option is available in Data ONTAP 8.1 and later.
> size | [0..2^63-1] | integer | New size for the LUN in bytes.
> space-reservation-enabled |  | boolean optional | By default, the lun is space-reserved. If it is desired to manage space usage manually instead, this can be set to "false" which will create a LUN without any space being reserved.

lun-create-from-file | [top]

> Create a lun from an existing file. A new lun is created, at the given lun path (which must be at a qtree root). A hard link is created to the existing file. The file contents are not copied or changed. The file can be resized to a larger size, rounding up to a cylinder boundary.

> Input Name | Range | Type | Description
> file-name |  | string | A fully qualified filer path to the file to create the LUN from. This must be in the same qtree as the LUN being created. The file must also be in the root of the volume or in a qtree/regular directory in the root of the volume or in a regular directory in a qtree.
> ostype |  | lun-os-type optional | The os type for the LUN. The default type if not specified is "image".

lun-create-from-snapshot | [top]

> Creates a LUN in the active file system. The lun has the same initial contents as the referenced snapshot copy of an existing lun. (Note that no copy of the data is made.) Future writes go into the new lun. Reads of unmodified data are satisfied from the snapshot location. Reads of modified data are satisfied by first attempting to find the required buffer in the new lun. If a buffer is not found (buffer corresponds to a hole), it is looked for in the snapshot copy instead.
