External Disks

---

Note -

The Netra software does not display the External Disks module if you do not have external disks attached to the Netra server. If you add a new external disk to a Netra server that is already configured, restart the server with the "Check for new devices during restart" option so that it recognizes the new disk drive.

---

Use the External Disks module to create mount points for external disks or to erase any unmounted disks. You must provide the mount point for a disk drive.

The External Disk module presents a graphic overview of the external disks attached to the system. Each disk is presented as a colored icon, and the icon color represents its state. The legend correlates the icon color to states described in the following table.

Table 9-1 External Disk State Color Code

Color	State	Comment
Green	Unused	Disk is available for formatting and mounting.
Red	System	Disk contains the Solaris operating environment.
Yellow	Erased	Disk has been formatted.
Aqua	Mounted	Disk is accessible through the file system hierarchy.
Orange	Not a Netra disk	Disk is not a Netra disk, but partially or totally mounted.
Purple	Meta	Disk which all or part is in use by a metadevice.
(blank)	Empty	No disk.

Above each disk icon is the disk name. If this name is a link, then by clicking the link, a list of valid operations for that disk is displayed. Only unused disks or disks that have already been erased/mounted by the Netra system show up as links.

Caution -

When you erase a disk, you lose all the data on it.
