Earlier I’ve demonstrated how to use 3PAR CLI with Powershell. In this example I will show how to work with 3PAR’s WSAPI via Powershell and poll last time remote copy group was synchronized (i use Last Sync date from first volume in the remote copy group).<\/p>\n
I was asked to create solution to monitor replication via Recovery Manager for SQL as it sometimes fails for whichever reason and we don’t get notification that our SQL server wasn’t synchronizing to DR side for a while. I have special place for this product from HP (read my earlier posts).<\/p>\n
If you’re using WSAPI to only read information, i recommend you create brand new account with limited privileges, as oppose to using 3paradm. <\/p>\n
If service shows as Disabled, run the following command: Now to Powershell example:<\/p>\n Earlier I’ve demonstrated how to use 3PAR CLI with Powershell.

\nFirst check if WSAIP is enabled. By default it is disabled, but can be easily enabled.
\ncli% showwsapi
\n-Service- -State- -HTTP_State- HTTP_Port -HTTPS_State- HTTPS_Port -Version-
\nEnabled Active Disabled 8008 Enabled 8080 1.4.2<\/code><\/p>\n
\ncli% startwsapi<\/code>
\nOptional, you can configure either http or https. I suggest only use https (in my example i use SSL and have code to deal with self signed certs)
\ncli% setwsapi -http enable
\ncli% setwsapi -https enable<\/code><\/p>\n\r\n# Name: 3PAR_RC_Check.ps1\r\n# Author: Naz Snidanko\r\n# Date Created: Nov 11, 2015\r\n# Date Modified: \r\n# Version: 0.1\r\n# Description: uses WSAPI to poll last sync of the 3par group.
