Which command would add redundancy to the pool1 storage pool?
The server has two spate 140-GB disk drives: c3t5d0 c3t6d0
Which command would add redundancy to the pool1 storage pool?
Correct Answer: A
Explanation/Reference:
Explanation:
You can convert a non-redundant storage pool into a redundant storage pool by using the zpool attach command.
Note: zpool attach [-f] pool device new_device
Attaches new_device to an existing zpool device. The existing device cannot be part of a raidz configuration. If device is not currently part of a mirrored configuration, device automatically transforms into a two-way mirror of device and new_device. If device is part of a two-way mirror, attaching new_device creates a three-way mirror, and so on. In either case, new_device begins to resilver immediately.

The correct answer should be B as the zpool attach command is defined as follows:
zpool attach <pool_name> <existing device> <new device>
# zpool attach pool1 c3t3d0 c3c5d0 - mirror first disk
# zpool attach pool1 c3t4d0 c3t6d0 - mirror second disk
therefore to mirror both disks, the following commands needs to be issued:
