IBM SVC data source

The IBM SVC data source collects inventory and performance data using SSH, supporting a variety of devices that run the SVC operating system. The list of supported devices includes models such as the SVC, the v7000, the v5000, and the v3700. Refer to the Insight data source support matrix for supported models and firmware versions.

Terminology

OnCommand Insight acquires the following inventory information from the IBM SVC data source. For each asset type acquired by Insight, the most common terminology used for this asset is shown. When viewing or troubleshooting this data source, keep the following terminology in mind:

Vendor/Model Term	Insight Term
Drive	Disk
Cluster	Storage
Node	Storage Node
Mdisk Group	Storage Pool
Vdisk	Volume
Mdisk	Backend LUN

Note: These are common terminology mappings only and might not represent every case for this data source.

Inventory Requirements

IP address of each SVC cluster
Port 22 available
Public and private key pair that you either generate withInsight or reuse a keypair already in use on your SVC
If you are reusing an existing keypair, you must convert them from Putty format to OpenSSH format.
Public key installed on the SVC cluster
Private key needs to be identified in the data source
Access validation: Open ssh session to the SVC cluster using the private key

Note: No third-party software needs to be installed.

Performance Requirements

SVC Console, which is mandatory for any SVC cluster and required for the SVC discovery foundation package.
Administrative access level required only for copying performance data files from cluster nodes to the config node.
Note: Because this access level is not required for the SVC foundation discovery package, the SVC foundation user might not work successfully.
Port 22 required
A private and public SSH key must be generated for this user, and the private key stored so that it is accessible from the Acquisition Unit. If the SVC foundation user has the proper permissions, then the same user and key works. The same SSH key can be used for inventory and performance data.
Enable data collection by connecting to the SVC cluster by SSH and running: svctask startstats -interval 1
Note: Alternatively, enable data collection using the SVC management user interface.
