You can use the snapmirror resync command to reestablish the connection between the source and the destination. This command is applied after the SnapMirror relationship between the source and destination is broken.

The command to create a 64-bit aggregate is the same aggr create command that is present in Data ONTAP 7G for aggregate creation. The aggr create command has a new flag, -B, to specify the type of aggregate to create. It takes a value of either 32 or 64 and creates the respective type of aggregate. Therefore the aggr create command with -B 64 creates a 64-bit aggregate. The aggr create command without the -B flag by default creates a 32-bit aggregate.

Here are some commands for creating different aggregate types in Data ONTAP 8.0:

Creating a 64-bit aggregate:

aggr create aggr_64 -B 64 5

Creating a 32-bit aggregate using –B flag:

aggr create aggr_32 -B 32 5

Creating a 32-bit aggregate without using –B flag:

aggr create default_aggr_32 5

Note: the man pages do not include this option in later versions of DOT because 64-bit is now the default.

To convert an asynchronous SnapMirror relationship to a synchronous SnapMirror relationship, on the administration host, edit the snapmirror.conf file on the destination system to change the schedule to sync.

The data structures that are backed up and restored through SnapVault depend on the primary system.

On systems running Data ONTAP, the qtree is the basic unit of SnapVault backup and restore.

SnapVault backs up specified qtrees on the primary system to associated qtrees on the SnapVault secondary system. If necessary, data is restored from the secondary qtrees back to their associated primary qtrees.

On open systems storage platforms, the directory is the basic unit of SnapVault backup. SnapVault backs up specified directories from the native system to specified qtrees in the SnapVault secondary system.

If necessary SnapVault can restore an entire directory or a specified file to the open systems platform.

The destination system uses a slightly more disk space and directories than the source system.

disk show [ -o | -s | -n | -v | -a]

Used to display information about the ownership of the disks. Available only on systems with software-based disk ownership. -o lists all disks owned by the filer with the name -s lists all disks owned by the filer with the serial number -n lists all unassigned disks. -v lists all disks. -a lists all assigned disks.

Startup commands for your storage system are stored in the /etc/rc file. The /etc/rc file contains commands that the storage system executes at boot time to configure the system.

Commands in the /etc/rc file configure the storage system to:

Communicate on your network

Use the NIS and DNS services

Save the core dump that might exist if the storage system panicked before it was booted
