Mount point – You can change the directory where the filesystem will be mounted. The data is restored relative
to this directory, so the contents, if any will not change. You cannot change the mount point of the root (/),
/boot or /usr (if any) filesystems.

Device – Here you can select a new device where the filesystem should be created and/or restored. Possible
filesystem devices are disk slices,

meta-devices

(SVM) and

Zpool Virtual Devices

. When pressing F4 at this

field, you will get a list which contains the devices currently assigned and any devices that are not already
assigned. Press Enter on any line to assign the device to the filesystem.

Filesystem type – Here’s where you can select the type of filesystem to create. Only the filesystem types
supported by BOTH the boot media and the backup to be restored will be selectable within this field. Changing
this field will change the options while appear in the Additional options section below.

Mount optionsF4 at this field will display a lengthy list of mount options which apply to all filesystems as well
as additional mount options specific to the selected filesystem type. You can combine them in most cases, and
some options, when selected, will prompt you for additional input. In most cases, you can use “default”. Don’t
change these unless you know what you’re doing.

Additional Options – Various options such as block size, fragment size, label id, etc, will appear, based on the
filesystem type selected. The options vary for each filesystem, and the list of available selections under each
option will also vary depending on both the filesystem type and the other options selected.

Filesystem Size versus Device Size

The minimum filesystem size displayed at the bottom of the screen the size of the data in the original
filesystem that was backed up. The size of the device may have to be quite a bit larger depending on the
amount of space the filesystem metadata requires.

SBAdmin tries to keep track of the minimum size of the device based on the amount of data to be restored,
and this calculation varies based on the filesystem type and many other options that are configurable here.
If you change any of the options, such as the fragment size, block size, or number of bytes per inode in
a filesystem, the amount of free space may be adversely affected. Be sure you have plenty of free space
available (based on the size of the device) in case the change requires more space than the filesystem
previously needed.

When you have finished your changes, press F3 or ESC to return to the list of filesystems, then F3 or ESC
again to return to the

Change Settings

menu.

Change Swap Devices

Use this option to select the device or devices which should be used as swap devices (also known as swap
space
and paging space) on the system. Solaris supports disk slices,

meta-devices

and

ZFS volumes

for swap

devices. When selecting this option, a screen similar to the following will appear:
