QUESTION 108Which switch needs to be added to the vxdg -g diskgroup adddisk disk_name command to forceVeritas Volume Manager (VxVM) to take the disk media name of the failed disk and assign it to a replacementdisk?

A. -forceB. -kC. -fD. -assign


Explanation/Reference:vxdg [-g diskgroup] [-kp] [-f] [-o overridessb] adddisk [ medianame=]accessname...

The -f option must be specified if the disk already has a disk group tag name set. If the -k option is specified, the disk media name must represent a disk media record that was previouslydissociated from its disk access record with -k rmdisk; otherwise, a new disk media record is created torepresent the disk. With the -k option, plexes requiring recovery are flagged as stale.
