NSR_SERVICE(5)

NAME

NSR service − NetWorker server resource type “NSR”

SYNOPSIS

type: NSR

DESCRIPTION

Each NetWorker server is described by a resource of type NSR. See nsr_resource(5) for general information on NetWorker resources. To edit the NSR resource use the command:

nsradmin −c "type:NSR"

or use the nwadmin(8) GUI. See nsradmin(8) for information on using the NetWorker administration program.

ATTRIBUTES

The following attributes are defined for the NSR resource. The information in parentheses describes how the attribute values are accessed. Read-only indicates that the value cannot be changed by an administrator. Read/write means the value can be set as well as read. Choice list means that any number of values can be chosen from the given list. Static attributes change values rarely, if ever. Dynamic attributes have values which can change rapidly. Hidden means it is an attribute of interest only to programs or experts, and these attributes can only be seen when the hidden option is turned on in nsradmin(8) or details option is set in nwadmin(8). For example, an attribute marked (read-only, static) has a value which is set when the resource is created and never changes, or is changed only by the server.

name(read-only, static)
This attribute specifies the hostname of this NetWorker server.
Example name: mars;

version(read-only, dynamic)
This is the software version of the NetWorker server daemon, nsrd(8). This includes a slash and the number of clients currently licensed.
Example: version: NetWorker 4.1 Turbo/110;

save totals(read-only, dynamic, hidden)
Save statistics. A string containing the total number of save sessions, the number of saves with errors (if any) and the total number of bytes saved (if any). This attribute is updated after each save session completes.
Example: save totals: "37 sessions, 457 MB total";

recover totals(read-only, dynamic, hidden)
Recovery statistics. A string containing the total number of recover sessions, the number of recovers with errors (if any) and the total number of bytes recovered (if any). This attribute is updated after each recover session completes.
Example: recover totals: "347 sessions, 48 MB total";

totals since(read-only, dynamic)
The time statistics collection started. This is usually the last time the NetWorker server was rebooted.
Example: totals since: "Fri Jun 1 09:35:02 1992";

NSR operation(read-only, choice list, hidden)
This attribute is currently unused and is provided for backward compatibility.

parallelism(read/write, static)
This attribute sets the number of concurrent save sessions that this server will allow. The value can be set by an administrator. Use higher values for better performance on a fast system with lots of main memory and swap space, and use lower values to avoid overloading a slow system, or systems with little main memory and/or swap space. See sessions per device, below, for information on side-effects. Warning: due to bugs in some versions of Unix, high values of parallelism may cause the system to lock up.
Example: parallelism: 4;

active devices(read/write, static)
This attribute sets the number of concurrent devices this server will allow. The value can be set by an administrator. Use higher values for better performance on a fast system, and use lower values to avoid overloading a slow system. This value should never be larger than the total number of devices. This attribute is not changeable (i.e. forced to have the value one) unless the Concurrent Device Support (CDS) add-on module is enabled. See sessions per device, below, for information on side-effects.
Example: active devices: 3;

sessions per device(read/write, static)
This attribute gives a target number of saves for each device. Saves are allocated to each device in order, until this many are assigned, then the next device is used. Once all devices have this many assigned, they are allocated equally to each device. The value can be set by an administrator. Use higher values to multiplex many clients onto each tape; the value one spreads out the clients over as many devices as possible. A good rule of thumb is to set sessions per device, active devices, and parallelism such that sessions per device times active devices equals parallelism.
Example: sessions per device: 3;

manual saves (read/write, hidden)
This attribute allows the administrator to disable manual backups to the server. Scheduled backups continue to work normally.

message(read-only, dynamic, hidden)
The last message of any kind logged. A time stamp is included at the start of the string.
Example: message: "Mon 12:25:51 Tape full, mount volume mars.001 on /dev/nrst1";

message list(read-only, dynamic, hidden)
A list of recent messages, with a time stamp and a string message for each value.
Example: message: "Mon 12:25:51 Tape full, mount volume mars.001 on /dev/nrst1";

session(read-only, dynamic, hidden)
The value of this attribute is a list of session information strings. Each string includes the NetWorker client name, type of operation (saving, browsing, or recovering) and information about the save set, including name, number of bytes, and number of files. All sizes and rates are in bytes per second, Kilobytes (1024), Megabytes (a thousand Kilobytes), etc.
Example:

session: "venus:/usr saving to mars.001 20MB of 90MB",
"mars:/usr/src done saving 24MB of 244MB";"

pending(read-only, dynamic, hidden)
A list of events pending with the NetWorker event notification system (see nsr_notification(5)). The first three fields are the time, priority, and event name.
Example: pending: "Fri 14:40:15 alert: media mount of mars.001 suggested on /dev/nrst1";

status(read-only, dynamic, hidden)
A list of status flags for the NetWorker server. These flags are only for use by NetWorker server-side programs (e.g. savegroup) and list various features enabled in the running server. The format is currently name=boolean (true or false). The features listed, and their states, can change at any time.

statistics(read-only, dynamic, hidden)
A list of strings of the form name=number that give a number of server statistics.

types created(read-only, static)
A list of all the other resource types this NetWorker server can create and about which clients can query.
Example: types created: NSR device, NSR group;

administrator(read/write, static)
This is a list of names (or netgroups) of users who are allowed to administer NetWorker. Normally this list is inherited by all other resources on this server, although each administrator attribute can be explicitly changed if desired. Administrators can change the values of attributes for the resource which lists them. The administrator list also determines who can add and delete resources of the other NSR types. The user "root" on the local host of the server is always an administrator. Entries specifying other administrators are of the form, user, user@host, host/user, or &netgroup. The user name and/or host name may be a wild card, "∗" (any user and/or host). Entering just a user name allows that user to administer NetWorker from any host (equivalent to user@∗ or ∗/user). Netgroup names are always preceded by an "&". The following example grants NetWorker administrative privileges to, "root" from any host, the user "operator" from the hosts "jupiter" and "mars", the user "admin" from any host, and all <user name, user’s hostname, server’s domain> in the netgroup "netadmins".
Example: administrator: root, operator@jupiter, mars/operator, admin@∗, &netadmins;

mm op message(read/write, dynamic, hidden)
This attribute lists the descriptive message for the most recently completed media database operation. The NetWorker program (such as nsrmm(8)) that requested the operation clears this attribute as soon as it has read the result. An administrator should never change this attribute manually.

mm operation value (read/write, dynamic, hidden)
This attribute is used by programs such as nsrmm(8) to pass the desired media database operation location or flags to the NetWorker server. The value is automatically cleared when the operation completes. An administrator should never change this attribute manually.

mm operation(read/write, choice list, dynamic, hidden)
This attribute is used by programs such as nsrmm(8) to pass the media database operation type currently desired to the NetWorker server. The possible choices are: purge volume, purge save set, delete volume, delete save set, mark volume, mark save set, unmark volume, unmark save set, specify volume lcoation, specify volume flags, and specify save set flags. The server serializes such operations and performs the appropriate queries on nsrmmdbd(8). The value is automatically cleared when the operation completes. An administrator should never change this attribute manually.

mm operation id(read/write, dynamic, hidden)
This attribute is used by programs such as nsrmm(8) to pass the desired media database operation identifier to the NetWorker server. The value is automatically cleared when the operation completes. An administrator should never change this attribute manually.

enabler code(read/write, dynamic, hidden)
This attribute specifies the enabler code for the base enabler of the server software.
