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.
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.
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.
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.


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.

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.
This is the network name of the system that NetWorker is running on. It is case-sensitive.
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.
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.


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


nsrjb(1m), jbconfig(1m), libstlstk(1m), mini_el(1m), ssi(1m), libstlibm(1m)  


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