ABC.com has An HP-UX 9000/800 host that currently uses multi-pathed storage provisioned from
a Symmetrix 8830. All LUNs are presented to the host application utilizing Veritas Volume
Manager. ABC.com is replacing the storage array with a DMX1000, and this will require a data
migration effort. The host is running numerous 24×7 applications and has to be online during the
migration. You are considered the following two approaches:host-based mirror/split of the Veritas
volumesarray-based SRDF What drawback does using host-based volume mirroring have for the
migration?

A.
Requires lots of internal disks, where writes are buffered until initial sync is complete

B.
Consumes host CPU cycles and I/O resources; this could adversely impact applications

C.
Could result in corruptedfilesystems with write-intensive workloads during the migration

D.
The volume copy process requires four block writes for every block read
