   A company has a virtual volume that is part of a consistency group. The volume is used by a database application that requires continuous availability. The administrator needs to expand the volume. What is the recommended approach to minimize disruption?

   • ACreate a new volume and migrate the data, then delete the old volume.
   • BExpand the volume online using Unisphere or VPlexcli, ensuring the host uses multipathing.
   • CExpand the volume using the storage array's native tools, not Metro Node.
   • DTake the consistency group offline, expand the volume, and bring it back online.

   A company has a virtual volume that is part of a consistency group used by a mission-critical database. The volume is currently 1 TB and needs to be expanded to 2 TB. The database vendor requires that all volumes in the consistency group be the same size. The administrator plans to expand the volume using Unisphere. What is the best approach?

   • ACreate a new consistency group with the expanded volume and migrate the data.
   • BExpand only the target volume to 2 TB and leave the others at 1 TB.
   • CExpand all volumes in the consistency group to 2 TB to maintain consistency.
   • DRemove the volume from the consistency group, expand it, and add it back.

   After issuing a volume expansion command in VPlexcli, what should the administrator do to ensure the command was accepted?

   • AReboot the Metro Node cluster to apply the change.
   • BCheck the command output for a success message or confirmation.
   • CRun the `volume delete` command to verify the volume still exists.
   • DRe-export the volume to all hosts to make the new size visible.

   After expanding a volume using Unisphere, an administrator checks the volume properties in Unisphere and sees the new size. However, the host still shows the old size. The host is running Linux with device-mapper multipathing. What should the administrator do to make the new capacity visible to the host?

   • ARun 'partprobe' or rescan the SCSI devices on the host.
   • BRun 'volume expand' again with the same size to refresh the host.
   • CCheck the storage array's native tools to confirm the expansion.
   • DReboot the host to force a rescan.
