This chapter provides a short description in terms of manual pages of the FIERA CCD Controller utilities.

This shell script allows a user to dump/restore a whole disk of a
Sparc running FIERA (SLCU). It is assumed that the scsi id of the disk
to dump/restore is 3. The script must be run as root and on a Sparc
running Solaris 2.x.
The parameter remote_host refers to host to which the tape device
is physically connected. This host may be either a Sun or an Hp
workstation. In case of a dump operation, remote_host must be
specified. In the case of a restore operation this parameter is
optional and, if not specified, defaults to the local host.
As the disks of SLCUs are usually of 4 Gb size, it is foreseen for the
dump operation the usage of a DDS2 (120m, 4 Gb native capacity)
cassette. It is strongly advised to use a DDS2 device to dump the
disk.
Remote dump/restore operation are performed as FCDDUMPUSER. So access
to the remote host as FCDDUMPUSER must be allowed. No restriction is
enforced on the choice of FCDDUMPUSER as long as this user has access
to the tape device. The environment variable FCDDUMPUSER must be set
by the user before running the script. If it is not set, the script
will use a default: "fcdrun".
The correspondence among devices and file systems is defined as
follows:

/dev/rdsk/c0t3d0s0 /
/dev/rdsk/c0t3d0s6 /usr
/dev/rdsk/c0t3d0s4 /var
/dev/rdsk/c0t3d0s7 /export/home
/dev/rdsk/c0t3d0s5 /opt
/dev/rdsk/c0t3d0s3 /usr/openwin

These are the file systems which will be dumped/restored. These are
also the only file systems needed in order to have an exact replica of
the original system.
Disks on which the tape are restored are formatted so that all data
previously contained are lost. The disks must be partitioned
beforehand. Hereafter are included the partition tables of the
models of some disks currently used by FIERA systems.

In case it should be necesary to partion a disk of another type, this
operation should be done taking into account the following:
1. Total disk size must be equal or greater than 4 Gb.
1. Partions number, name and flags must be the same as in the previous
table.
2. Partions size must be equal or greater. If disk size does not allow
it, swap could be decreased.

If in doubt, follow the partition table as suggested in the VLT
Solaris Installation Manual - VLT-MAN-ESO-17200-1646.
As a rule of thumb for the swap: its size should be double the size
of the installed RAM.

Instruction on how to partition a disk may be found in Solaris 2.x
documentation e.g. in the man pages relative to format(1M). Refer to
FIERA maintenance manual for details on how to partition a disk.
The environment variable FCDDUMPTAPE and FCDRESTORETAPE may be used to
specify the device on which to perform backups. A no-rewind device
must be specified for dump and a rewind device for restore.
If not defined the devices are:
on HPs:
/dev/rmt/0lbn for dump
/dev/rmt/0lb for restore
on Suns:
/dev/rmt/0mnb for dump
/dev/rmt/0mb for restore
