Creating Jaz Data Disks

A Jaz disk must be initialized before it can serve as a data disk for archiving ISS data. Much of the initialization is similar to creating a distribution Jaz disk. The disk can be optionally formatted, it must be partitioned, and several directories must be created on it which the archiving scripts and programs expect. Hence the same script which handles backups and distributions also creates data disks, /iss/scripts/jaz_install. Normally though, the script will not be run directly; instead it will be run via the jaz command. (See Jaz Utilities.)

iss1>  jaz data

This will start the script and automatically choose to create a data disk, verified by this prompt:

About to create a data disk...
Continue (y/n) [y]?

Similar to backups and installations (Installation Format Step), the script steps through the formatting, partitioning, and filesystem creation for the Jaz data disk. The output will appear similar to the following example. Note that the low-level format step is skipped, as will virtually always be the case.

Done.  Data disk has been created.

The last series of commands simply creates the necessary directories on the Jaz disk.

When finished, the script ejects the data disk. The disk is now ready to be mounted and used by the archiver, as described in Swapping Data Disks.
