  populated with the hostname of the secondary using the OSSV Configurator utility. When using this option, make sure the "Check QSM Access List" box is enabled. The snapvault.access option on the NetApp secondary can be used to

  restrict the OSSV hosts that are allowed to initiate restores from that secondary system. This option can be populated with a list of hostnames for each OSSV host.

  For example:

  options snapvault.access host=ossv1,ossv2,ossv3

  http://www.uow.edu.au/~blane/netapp/ontap/cmdref/man1/na_options.1.htm update [ -S source ] [ -k kilobytes ] [ -s src_snap ] [ -c create_dest_snap ] [ -w ] destination For asynchronous mirrors, an update is immediately started from the source to the destination to update the mirror with the contents of the source.

  For synchronous mirrors, a snapshot is created on the source volume which becomes visible to clients of the destination volume.

  The update command must be issued on the destination node.status [ -l | -t | -q ] [ volume | qtree ... ] Reports status of all the SnapMirror relationships with a source and/or destination on this node. This command also reports whether SnapMirror is on or off. If any volume or qtree arguments are given to the command, only the SnapMirror relationships with a matching source or destination will be reported. If the argument is invalid, there won't be any status in the output.initialize [ -S source ] [ -k kilobytes ] [ -s src_snap ] [ -c create_dest_snap ] [ -w ] destination Starts an initial transfer over the network. An initial transfer is required before update transfers can take place. The initialize command must be issued on the destination node. If the destination is a volume, it must be restricted (see na_vol(1) for information on how to examine and restrict volumes). If the destination is a qtree, it must not already exist (see na_qtree(1) for information on how to list qtrees). If a qtree already exists, it must be renamed or removed (using an NFS or CIFS client), or snapmirror initialize to that qtree will not work.snapmirror.access

  This option determines which SnapMirror destination filers may initiate transfers, and over which network interfaces. When set to "legacy", SnapMirror uses the older snapmirror.allow to determine access. The option value is a string containing an expression which provides the access filter. An example of the options command for snapmirror.access is options snapmirror.access host=toaster,fridge. The default value is "legacy". See na_snapmirror(1) , na_snapmirror.allow

  (5) and na_protocolaccess(8) for more details.

  The snapmirror.allow file exists on the source filer used for SnapMirror.

• Question 107:

  Which exportfs command will temporarily export the resource while ignoring the options specified in the / etc/exports file?

  A. exportfs -a
  B. exportfs -i
  C. exportfs -u
  D. exportfs -v
  B. exportfs -i

• Question 108:

  The snapvault restore command is run on the _________.

  A. secondary system to push data to the primary system
  B. primary system to pull data from the secondary system
  C. secondary system to pull data from the primary system
  D. secondary system to push data to the primary storage system
  B. primary system to pull data from the secondary system

  The snapvault command has a number of subcommands. The set of subcommands differs on the primary and secondary.

  On the primary, the subcommands allow users to configure and manage a set of snapshots for potential replication to the secondary, to abort replication transfers to the secondary, to check status, to restore data from the secondary, and to

  release resources when a primary qtree will no longer be replicated to a secondary.

  On the secondary, the subcommands allow users to configure and manage the replication of primary paths to secondary qtrees, to configure and manage the snapshot schedules which control when all the qtrees in a secondary volume are

  updated from their respective primary paths and how many snapshots to save, to abort transfers, to check status, and to release resources preserved to restart backups from a restored qtree.

• Question 109:

  To automatically export volumes and directories on storage system reboot, include them in the /etc/exports file.

  A. True
  B. False
  A. True
