Disk installation and formatting
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.
For Solaris SPARC systems, if a disk is not formatted, the status field in the vxdisk list output shows as nolabel. The disk must be formatted before you add it to VxVM control.
SCSI disks are usually preformatted. Reformatting is needed only if the existing formatting has become damaged.
