APIs in Category: dp-throttle |
API version 3.8 |
dp-throttle-create |
This set of API's is used to manage and retrieve throttle schedule values. dp-throttle is to be used by the scheduler in conjunction with dp-schedule to determine the time and throughput of a specific backup. Throttle value can be changed throughout the day/week. Hence, each throttle schedule may contain multiple entries to indicate different time ranges and throughputs. The scheduler will also utilize the information to adjust the throughputs of the running tasks accordingly. |

| Element definition: obj-name-or-id | [top] |
Name or internal ID of a DFM object. This typedef is an alias for the builtin ZAPI type string. An obj-name-or-id must contain between 1 and 64 characters, and must conform to one of the following formats: Elements of type obj-name-or-id are used only as inputs to ZAPIs. The value must match either the name or internal ID of an existing DFM object. The ZAPI must specify the object's DFM object type (e.g. dataset, host, DP policy, etc.). Some ZAPIs allow the object to be one of several different types.
- It must have the format of an obj-name, or
- It must be the decimal numeric string form of a positive integer whose value is in the range [1..2^31 - 1].
If the format of an obj-name-or-id input element does not conform, or the value does not match the name or ID of an existing object, then generally the ZAPI documents that it fails with error code EOBJECTNOTFOUND. A ZAPI may return more specific error codes. In such cases, the ZAPI specification must document its behavior.
If a ZAPI can accept a null value (e.g. reference to no object at all) for such an element, then the element is declared optional, and the absence of the input element represents a null value.
[none]
| Element definition: throttle-assignee | [top] |
Description of a DFM object using the DP throttle.
Name Range Type Description assignee-full-name obj-full-name
Full name of a DFM object. assignee-id obj-id

Attributes of a throttle schedule
Name Range Type Description is-modifiable boolean
optional
If false, this throttle is one of the sample throttle that is created at installation time, therefore it may not be modified, renamed or destroyed. If true, it is not one of the sample throttles, therefore it may be modified, renamed or destroyed. is-modifiable always appears in the output. It is not possible to use it as input. throttle-description string
optional
Description of the throttle. It may contain from 0 to 255 characters. The description always appears in the output. If the description is omitted, then the default value is the empty string "". throttle-id integer
optional
ID of the throttle schedule. Element is ignored for throttle-create. Range: [1..(2^31)-1] throttle-item-list throttle-item-info[]
List of individual throttle items to be added throttle-name string
Name of the throttle schedule

| Element definition: day-info | [top] |
The attributes of a day list
Name Range Type Description day integer
day of the week. Range: [0..6]. (Sun = 0)
| Element definition: obj-full-name | [top] |
Full name of a DFM object. This typedef is an alias for the builtin ZAPI type string. An object full name conforms to all the rules of an obj-name, except that the full name may be up to 255 characters long. DFM creates full names by concatenating an object name with any parent object names, so as to create a unique name for an object. The format of full names is as follows:
- Host full names are the either the fully-qualified domain name or the IP address of the host.
- Aggregate full names are the host name and the aggregate name, separated by a colon, e.g. hostname:aggr0.
- Volume full names are the host name and the volume name, separated by ":/", e.g. hostname:/volume. Note this does not include "/vol". Volume and aggregate full names are distinguished by the presence of a forward slash after the colon.
- Qtree full names are the containing volume full name and the qtree name, separated by a slash, e.g. hostname:/volume/qtree. The data not contained by any qtree may be represented by "-", e.g. hostname:/volume/-.
- Lun Path full names are either a volume or qtree full name and the LUN path, separated by a slash, e.g. hostname:/volume/LUN or hostname:/volume/qtree/LUN.
- Network full names are a network address block in CIDR format, e.g. 1.2.3.0/8.
- OSSV Directory full names are the OSSV host name and the OSSV path, separated by a colon, e.g. host-lnx:/usr/local or host-w2k:c:/temp
- Include any others here...
- Initiator Group full names are host name and the initiator group name, separated by a colon, e.g. hostname:igroup.
For any DFM object not listed above, the obj-name and obj-full-name are identical.
[none]
| Element definition: obj-id | [top] |
Identification number (ID) for a DFM object. This typedef is an alias for the builtin ZAPI type integer. Object IDs are unsigned integers in the range [1..2^31 - 1]. In some contexts, an object ID is also allowed to be 0, which is interpreted as a null value, e.g., a reference to no object at all. The ID for a DFM object is always assigned by the system; the user is never allowed to assign an ID to an object. Therefore, an input element of type obj-id is always used to refer to an existing object by its ID. The ZAPI must specify the object's DFM object type (e.g. dataset, host, DP policy, etc.). Some ZAPIs allow the object to be one of several different types.
If the value of an obj-id input element does not match the ID of any existing DFM object of the specified type or types, then typically the ZAPI fails with error code EOBJECTNOTFOUND. A ZAPI may deviate from this general rule, for example, it may return a more specific error code. In either case, the ZAPI specification must document its behavior.
