Installing and Formatting Disks
Depending on the hardware capabilities of your disks and of your
system, you may either need to shut down and power off your system
before installing the disks, or you may be able to hot-insert the disks into
the live system. Many operating systems can detect the presence of the
new disks on being rebooted. If the disks are inserted while the system is
live, you may need to enter an operating system-specific command to
notify the system.
If the disks require low- or intermediate-level formatting before use, use
the operating system-specific formatting command to do this.
NOTE SCSI disks are usually preformatted. Reformatting is needed only if the
existing formatting has become damaged.
The following sections provide detailed examples of how to use the
vxdiskadm utility to place disks under VxVM control in various ways
and circumstances.
