An administrator is using VPlexcli to expand a volume that is part of a consistency group. The volume is currently 1 TB and needs to be expanded to 2 TB. The administrator runs the command 'volume expand --volume vol_cg --size 2T'. The command succeeds, but the host still shows 1 TB. What is the most likely reason?

The host has not rescanned the storage and the filesystem has not been extended.

The command failed because volumes in consistency groups cannot be expanded.

The volume is part of a consistency group, so the expansion only applied to one leg.

The host is using a single path and needs a reboot to see the new capacity.

A storage administrator is expanding a virtual volume using Unisphere. The volume is currently 500 GB and is used by a critical application. The administrator wants to ensure the expansion does not affect the application. What should the administrator do before performing the expansion?

Create a backup of the volume before expanding.

Verify that the host has a supported multipathing driver and that the volume is not in a snapshot.

Take the application offline and stop all I/O to the volume.

Ensure the volume is not part of a distributed device.

After expanding a volume using Unisphere, an administrator verifies the new size in Unisphere. However, the host still shows the old size. The host is running Linux with device-mapper multipathing. The administrator runs 'partprobe' but the size does not change. What should the administrator do next?

Run 'volume expand' again with the same size to refresh the host.

Rescan the SCSI devices using 'echo 1 > /sys/class/scsi_device/.../device/rescan' or use 'sg3_utils'.

Reboot the host to force a rescan.

Check the storage array's native tools to confirm the expansion.
