HP 3PAR Web Service API 1.3.1 Developer's Guide

(1) * (maximum number of sessions per node)
◦ Four-node or eight-node clusters:
If n is the number of nodes on these systems, then:
– If the master and network nodes are on the same machine, then the number of nodes
processing the request will be n - 1, and the total number of WSAPI sessions will be:
(n - 1) * (maximum number of sessions per node)
– If the master and network nodes are on separate machines, then the number of nodes
processing the request will be n - 2, and the total number of WSAPI sessions will be:
(n - 2) * (maximum number of sessions per node)
On the HP 3PAR StoreServ 10400 Storage (after December 2013) and the HP 3PAR
StoreServ 10800 Storage, the WSAPI server excludes the network and master nodes
from processing HTTP requests. (The sole exception is that the network node will process
an HTTP GET request for WSAPI configuration information.) Consequently, these nodes
do not enter the maximum-session calculation.
The maximum number of sessions that the WSAPI server can handle at any given time can be
queried by using an HTTP GET operation. For more information, see “Getting WSAPI Configuration
Information” (page 129).
Deleting a Session Key
When a client is finished making requests to the server it should delete the session keys it created.
This frees up server resources and allows for better server performance.
NOTE: Unused session keys expire automatically after fifteen minutes.
To delete a session key, send a request with the HTTP DELETE method and the URI:
https://<storage_system>:8080/api/v1/credentials/<session key>
where <session key> is the key that is returned in the process of creating a session key. For
more information, see “Creating Credentials” (page 38).
Session Key Deletion Success
A successful session key deletion returns the HTTP status code 200 OK, without a message body.
Session Key Deletion Errors
An error condition returns an error object as a message body.
Example
To delete credentials using cURL, enter the following command (as a single line):
curl -X DELETE -H "Accept: application/json"
https://<storage_system>:8080/api/v1/credentials/1-c86aedb2e7e98b41-b06d2d50
