Because volume SnapMirror works at the block level, the source and destination must both be FlexVol volumes in the same aggregate type. The source and destination of a volume SnapMirror relationship must either both be FlexVol volumes in 32-bit aggregates or both be FlexVol volumes in 64-bit aggregates.

Therefore you cannot create a volume SnapMirror relationship from a FlexVol volume in a 32-bit aggregate to a FlexVol volume in a 64-bit aggregate or vice versa.

aggr mirror aggrname

[ -f ]

[ -n ]

[ -v victim_aggrname ]

[ -d disk1 [ disk2 ... ] ]

Turns an unmirrored aggregate into a mirrored aggregate by adding a plex to it. The plex is either newlyformed from disks chosen from a spare pool, or, if the -v option is specified, is taken from another existing unmirrored aggregate. Aggregate aggrname must currently be unmirrored. Use aggr create to make a new, mirrored aggregate from scratch.

Disks may be specified explicitly using -d in the same way as with the aggr create and aggr add commands.

The number of disks indicated must match the number present on the existing aggregate. The disks specified are not permitted to span disk pools. This behavior can be overridden with the -f option. The -f option, in combination with -d, can also be used to force using disks that have a rotational speed that does not match that of the majority of existing disks in the aggregate.

If disks are not specified explicitly, then disks are automatically selected to match those in the aggregate's existing plex.

The -v option can be used to join victim_aggrname back into aggrname to form a mirrored aggregate. The result is a mirrored aggregate named aggrname which is otherwise identical to aggrname before the operation.

Victim_aggrname is effectively destroyed. Victim_aggrname must have been previously mirrored with

aggrname, and then separated via the aggr split command. Victim_aggrname must be offline. Combined with the -v option, the -f option can be used to join aggrname and victim_aggrname without prompting the user.

The -n option can be used to display the command that the system will execute without actually making any changes. This is useful for displaying the automatically selected disks, for example.

fcp show adapter [ -v ] [ adapter ]

If no adapter name is given, information about all adapters are shown.

This command displays information such as nodename/portname and link state about the adapter.

If the -v flag is given, this command displays additional information about the adapters.

snapmirror resume destination

Resumes transfers to destination. The snapmirror resume command can be used either to abort a

snapmirror quiesce in progress or undo a previously completed snapmirror quiesce. The command restores the state of the destination from quiescing or quiesced to whatever it was prior to the quiesce operation.

A volume SnapMirror relationship is not allowed between two SnapLock Compliance volumes if the destination volume has unexpired files.

igroup show [ -v ] [ initiator_group ] Displays the nodes in an initiator group and their aliases, set with the fcp wwpnalias command. If no initiator_group is specified, the members of all initiator groups are displayed. You can use the -v option to get a verbose listing.

lun show [ -v | -m | -c ] [ all | mapped | offline | online | unmapped | staging |

-g initiator_group | -n node | -l vol_name | lun_path ] Displays the status (lun_path, size, online/offline state, shared state) of the given LUN or class of LUNs. With the -v option supplied, additional information (comment string, serial number, LUN mapping, HA Pair Shared Volume Information) is also displayed. With the -m option supplied, information about lun_path to initiator_group mappings is displayed in a table format. With the -c option supplied, information about LUN cloning status is displayed.

In takeover mode, this network interface assumes the identity of the network interface on the partner

For the partner interface configuration to be persistent across reboots, you must include the ifconfig command in the /etc/rc file

Sadly, you cannot convert a LUN into a Vulcan Language Dictionary.

-s

Display a summary of the output columns upon termination, descriptive columns such as `CP ty' will not have summaries printed. Note that, with the exception of `Cache hit', the `Avg' summary for percentage values is an average of percentages, not a true mean of the underlying data. The `Avg' is only intended as a gross indicator of performance. For more detailed information use tools such as na_nfsstat, na_netstat, or statit.
