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

The following commands are available in the aggr suite:

If you use the -d disk1 [ disk2 ... ] argument, the node creates the aggregate with the specified spare disks disk1, disk2, and so on. You can specify a space-separated list of disk names. Two separate lists must be specified if the new aggregate is mirrored. In the case that the new aggregate is mirrored, the indicated disks must result in an equal number of disks on each new plex.

The disks in a plex are not permitted to span spare pools. This behavior can be overridden with the -f option.

The same option can also be used to force using disks that do not have matching rotational speed. The –f option has effect only when used with the -d option specifying disks to use.

The -m option can be used to specify that the new aggregate be mirrored (have two plexes) upon creation. If this option is given, then the indicated disks will be split across the two plexes. By default, the new aggregate will not be mirrored.

aggr mirror aggrname

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.

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.

You use the snapvault restore command to restore a backed-up qtree saved to the secondary system. Starting with Data ONTAP 7.3, you can restore the data to an existing qtree on the primary system using baseline restore or incremental restore.

The snapmirror.access option is the preferred method for controlling snapmirror access on a snapmirror source filer.

Both ‘warn you that there are no available spares from the proper pool’ and ‘halt after 24 hours if spare disk are not added to the proper pool’ are correct answers. However, since Data ONTAP alerts you first, 'warn you that there are no available spares' is the best answer.

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.

In order to test or effect a Disaster Recovery operation, you must restrict access to the disaster site node to prevent the node from resuming service. If you do not, you risk the possibility of data corruption.

Access to the disaster site note can be restricted in the following ways:

Turn off the power to the disaster site node Use "manual fencing" (Disconnect VI interconnects and fiber channel cables; either physically or through configuration changes on the fabric switches.)

Isolating the failed node from the surviving node could still lead to the possibility of a split brain, so this is not a correct answer.

sysstat reports aggregated filer performance statistics such as the current CPU utilization, the amount of network I/O, the amount of disk I/O, and the amount of tape I/O.

Negotiated failover is a general facility which supports negotiated failover on the basis of decisions made by various modules.

cf.takeover.on_disk_shelf_miscompare

This option allows negotiated takeover to be enabled when the cluster nodes detect a mismatch in disk shelf count. By default, this option is set to off.

This option is available only when cluster is licensed and changing the value on one filer automatically changes the value on the partner filer.

You can export any file path. Implicitly file paths are filesystem objects. You can export a directory, a qtree, a volume or even a file.

fcp show initiator [ -v ] [ adapter ]

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

The command displays the portname of initiators that are currently logged in with the Fibre Channel target adapters. If the portname is in an initiator group setup through the igroup command, then the group name is also displayed. Similarly, all aliases set with the fcp wwpn-alias command for the portname are displayed as well.

If the -v flag is given, the command displays the Fibre Channel host address and the nodename/portname of the initiators as well.

snap restore [ -f ] [ -t vol | file ] [ -s snapshot_name ] [ -r restore_as_path ]

vol_name | restore_from_path

Reverts a volume to a specified Snapshot copy, or reverts a single file to a revision from a specified Snapshot copy.

Before reverting the volume or file, the user is requested to confirm the operation. The -f option suppresses this confirmation step.

Using the -p option may reduce the extra storage requirements in a flexible volume when reallocation is run on a volume with snapshots. It may also reduce the amount of data that needs to be transmitted by SnapMirror on its next update after reallocation is performed on a SnapMirror source volume.

In OnTap 8.0, when UNIX security style is selected, only UNIX security objects can be used. The correct answer is GID, UID and UNIX permissions.

Basic UNIX permissions are organized into three classes: user, group, and others.

UNIX operating systems identify users with a numerical value: a user identifier, also known as a UID or User ID. Each user is a member of a group of the same name as the user. Like UIDs, groups (GIDs) are also specified using a numerical value.

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.
