Discovering the association between enclosure-based
disk names and OS-based disk names
To discover the association between enclosure-based disk names and OS-based
disk names
◆
If you enable enclosure-based naming, and use the vxprint command to
display the structure of a volume, it shows enclosure-based disk device names
(disk access names) rather than OS-based names. To discover the operating
system-based names that are associated with a given enclosure-based disk
name, use either of the following commands:
# vxdisk list enclosure-based_name
# vxdmpadm getsubpaths dmpnodename=enclosure-based_name
For example, to find the physical device that is associated with disk ENC0_21,
the appropriate commands would be:
# vxdisk list ENC0_21
# vxdmpadm getsubpaths dmpnodename=ENC0_21
To obtain the full pathname for the block and character disk device from
these commands, append the displayed device name to /dev/vx/dmp or
/dev/vx/rdmp.
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.
Note: SCSI disks are usually preformatted. Reformatting is needed only if the
existing formatting has become damaged.
