DESCRIPTION
dasadmin
This is not a complete listing of all possible dasadmin commands, but
does include those commands that are of use with NetWorker. For a
complete discussion, see the DAS Installation and Administration guide
provided by ADIC, EMASS or Grau.
mo[unt] [ -t type ] volser [ drive-name ]
Mounts the tape with the barcode label of volser into either
the first available drive (if drive-name is not specified) or
into the drive specified by drive-name. If the tape is not the
type defined by DAS_MEDIUM or ACI_MEDIA_TYPE, you can use the
-t type option to get the tape mounted. If the type of the
tape and the defined type for the drive do not match, the silo
will not load the tape. Note that the drive you are attempting
to use must be allocated for your use before you can mount or
dismount tapes. See listd and allocd below.
dism[ount] [ -t type ] volser | -d drive-name
Dismounts the tape that is either specified by volser or
whatever is in the drive specified by drive-name. If the tape
or drive are of a different type than your default, use the -t
type parameter. As with mount, you must have the drive
allocated to you to use this command.
ej[ect] [ -c ] [ -t type ] volser-range area-name
Ejects one or more tapes to the specified eject area. As with
other commands, if the type of the tape you are ejecting is
different from that defined by DAS_MEDIUM or ACI_MEDIA_TYPE,
you will need the -t type option. The -c specifies a
'complete' ejection for the specified volsers. A complete
ejection removes the entry for that volser from the silo
controller's internal database. A NON-complete ejection will
eject the tape, but the volser's entry in the database will
remain, and the volser's state will be set to 'ejected'. This
is useful if you anticipate replacing the tape in the silo
soon.
in[sert] area-name
Moves all tapes that are currently in the specified insert
area-name from the insert area to the normal storage locations
for tapes.
inventory
Starts a full inventory of the silo. USE WITH CAUTION! An
inventory of this sort can take a very long time! An inventory
of a silo with 180 slots takes over 20 minutes.
view [ -t type ] volser
Displays the current status of volser, including the volser,
type, attribute, and coordinate.
all[ocd] drive-name UP|DOWN clientname
The allocd command is used to allocate and deallocate drives
for different clients. Before you can use a tape drive, the
drive must be allocd'ed UP for your system. If it is currently
allocd'ed UP for a different client, it must first be allocd'ed
DOWN for that client before being allocd'ed UP for your system.
You cannot allocd DOWN a drive that has a tape in it. The tape
must be dismounted first.
l[ist]d
listd or ld shows the current state of all the tape drives
defined in the silo. The information presented will include
the drive-name, the amu drive (the location in the silo),
status (UP or DOWN), type, client the drive is allocated to,
and the volser of any loaded tape.
show -op | -ac client-name
Shows the operational or access parameters for the specified
client-name. You must include either -ac if you wish to see
access parameters, or -op if you wish to see operational
parameters for the client-name. Access parameters include
volser ranges and drive ranges that the client-name is allowed
to use. Operational parameters include whether the client-name
has complete access, dismount privileges along with the IP
address entered for client-name.
list client-name
Lists any outstanding requests that have been made by client-
name. If there are any, they are shown, along with the request
number and type.
can[cel] request-id
Allows you to cancel an outstanding request, assuming that you
have the necessary privileges. Use the request-id that was
shown by the list command.
qversion
Shows the version of the DAS server that you are connected to
and the version of the ACI protocol you are using to talk to
DAS.
qvolsrange beginvolser endvolser count [ clientname ]
qvolsrange is the way to obtain a list of the volsers that are
available in the silo. beginvolser and endvolser are volsers
of the form "123456". To use the first available or the last
available, you can use "". count specifies the maximum number
of volsers you wish to see.
ENVIRONMENT VARIABLES
These environment variables affect the operation of the silo, and
since the processes that are using them include both the commands
the user will enter and the processes that are spawned from nsrd,
they need to be set in a location where they will be in place when
nsrd is started. The three DAS_ variables are used by libstlemass,
while dasadmin uses ACI_MEDIA_TYPE instead of DAS_MEDIUM.
For Solaris, the definitions should be placed in
/etc/rc.2/S95networker.
For AIX, the definitions should be placed in /etc/rc.nsr.
For HPUX, the definitions should be placed in
/sbin/rc2.d/S900networker.
DAS_SERVER
This is either the network name or the IP address of the system that
is running DAS. For a single silo, this will usually be the silo
controller system. In larger installations, there will probably be
only one DAS server for the whole network. It is case-sensitive.
DAS_CLIENT
This is the network name of the system that NetWorker is running on.
It is case-sensitive.
DAS_MEDIUM
This variable is used by libstlemass. It should be the same as
ACI_MEDIA_TYPE.
This is the type of tape drive you are connected to. If this is not
specified, the default value of DLT will be used.
ACI_MEDIA_TYPE
This variable is used by dasadmin. It should be the same as
DAS_MEDIUM.
This is the type of tape drive you are connected to. If this is not
specified, the default value of DLT will be used. Acceptable values
are the same as those listed under DAS_MEDIUM.
EXAMPLES
NOTE on ranges:
The dasadmin utility will accept volser ranges for some commands.
There are three acceptable variations for these ranges:
single volser: "000635"
multiple volsers: "000635, 000789, 098732"
true range: "000610 - 000745"
NOTE on area-name and drive-name:
area-names usually consist of a letter and 2 digits. The letter
corresponds to whether you are referring to an insert area ("I") or
an eject area ("E"). You will need to get the correct values from
your silo administrator before using them.
drive-names are essentially free-form labels created by whomever
installed the silo. They may or may not have any relevance to
physical reality, so you will need to see the silo admin to get the
correct names. If the silo admin is not available, you can get the
same information using dasadmin listd along with dasadmin show -op
client-name followed by dasadmin show -ac client-name commands.
To setup the environment variables necessary for silo operations:
setenv DAS_SERVER emask
setenv DAS_CLIENT aurora
setenv DAS_MEDIUM DLT
setenv ACI_MEDIA_TYPE DECDLT
To see a listing of all volsers available in the silo:
dasadmin qvolsrange "" "" 10000
To see the current status of the drives in the silo:
dasadmin listd
To change the allocation of a drive from client a4 to client aurora:
dasadmin allocd DLT1 DOWN a4
dasadmin allocd DLT1 UP aurora

The only available diagnostic information is error messages that
may be printed out by dasadmin and libstlemass in the course of
normal operations.
