  http://en.wikipedia.org/wiki/Logical_Unit_Number_masking Logical Unit Number Masking or LUN masking is an authorization process that makes a Logical Unit Number available to some hosts and unavailable to other hosts.

• Question 175:

  You are trying to do a single file SnapRestore for a file, but you are receiving an error message that the directory structure no longer exists. Which is the most likely ?

  A. Once the directory structure has been deleted, you cannot restore the file using single file SnapRestore. You must now SnapRestore the volume.

  B. Snapshot copies have been created since the original directory structure was deleted.

  C. You must recreate the directory structure before trying to restore the file.

  D. You cannot restore a file to an alternate location.

  Correct Answer: C

  You can restore a file only to the volume where it was originally located. The directory structure to which a file is to be restored must be the same as that specified in the path. If this directory structure does not exist, you must create it before restoring the file.

• Question 176:

  Which action will cause a currently in-sync SnapMirror relationship to fail out of sync?

  A. Running snapmirroe update on the source storage system.

  B. Running snapmirror release on the source storage system.

  C. Modifying the /etc/snapmirror.conf file for the relationship on the source storage system

  D. Modifying the /etc/snapmirror.conf file for the relationship on the destination storage system.

  Correct Answer: D

  https://library.netapp.com/ecmdocs/ECMP1196979/html/man1/na_snapmirror.1.html https:// library.netapp.com/ecmdocs/ECMP1196979/html/man5/na_snapmirror.conf.5.html snapmirror 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 snapmirror update command must be issued on the destination filer. snapmirror release source { filer:volume | filer:qtree } Tell SnapMirror that a certain direct mirror is no longer going to request updates. If a certain destination is no

  longer going to request updates, you must tell SnapMirror so that it will no longer retain a snapshot for that destination. This command will remove snapshots that are no longer needed for replication to that destination, and can be used to

  clean up SnapMirror-created snapshots after snapmirror break is issued on the destination side.

  The source argument is the source volume or qtree that the destination is to be released from. The destination argument should be either the destination filer and destination volume name or the destination filer and destination qtree path. You

  can use a line from the output of the snapmirror destinations command as the set of arguments to this command. The /etc/snapmirror.conf file exists on the node containing the mirror used for SnapMirror.

• Question 177:

  In a Fiber Channel configuration, the host's HBA is referred to as the ___________, and the storage system's HBA to as the _____________.

  A. Target, initiator

  B. Primary, secondary

  C. Initiator, target

  D. Secondary, primary

  Correct Answer: C

• Question 178:

  Which storage system command would display the WWPNs of hosts that have logged into storage system using a Fibre Channel connection?

  A. fcp config

  B. fcp initiator show

  C. fcp show i

  D. fcp show initiator

  Correct Answer: D

  https://library.netapp.com/ecmdocs/ECMP1196979/html/man1/na_fcp.1.html 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.

• Question 179:

  What SnapDrive does

  SnapDrive software integrates with the Windows Volume Manager so that NetApp filers can serve as virtual storage devices for application data in Windows 2000 Server and Windows Server 2003 environments.

  SnapDrive is dependent on the virtual disk service. The virtual disk service must be started on the host prior to installing SnapDrive. SnapDrive manages virtual disks (LUNs) on a NetApp filer, making these virtual disks available as local disks

  on Windows hosts. This allows Windows hosts to interact with the virtual disks just as if they belonged to a directly attached redundant array of independent disks (RAID).

  SnapDrive provides the following additional features:

  It enables online storage configuration, virtual disk expansion, and streamlined management. It integrates NetApp Snapshot technology, which creates point-in-time images of data stored on virtual disks. It works in conjunction with

  SnapMirror?software to facilitate disaster recovery from either asynchronously or synchronously mirrored destination volumes.

• Question 180:

  Identify the two commands that could be entered on the SnapMirror destination storage system. (Choose two)

  A. Options snapmirror.access on

  B. Options snapmirror.resync on

  C. Snapmirror initialize

  D. Snap mirror resync

  Correct Answer: CD

  https://library.netapp.com/ecmdocs/ECMP1196979/html/man1/na_snapmirror.1.html snapmirror 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 resync [ -n ] [ -f ] [ -S source ] [ -k kilobytes ] [ -s src_snap ] [ -c create_dest_snap ] [ -w ] destination Resynchronizes a broken-off destination to its former source, putting the destination in the snapmirrored state and making it ready for update transfers. The resync command must be issued on the destination node.
