About discovering LPAR and VIO in Arctera InfoScale Operations Manager
You can use Arctera InfoScale Operations Manager to configure LPAR server, and discover the information that is related to LPARs, VIO clients, and VIO servers in your data center. Agentless discovery of client LPARs and VIO servers is not supported.
Note:
The Arctera InfoScale Operations Manager supports only legitimate filename characters in an LPAR profile name. The special characters reserved for Operating System usage (for example space, "\", "$", "!", "&") are not supported. It is recommended to use upper and lower case alphabets, numeric values (0-9), "_" and "-" for the LPAR profile name.
LPAR discovery mechanisms can be grouped into the following categories:
Discovery using the Hardware Management Console (HMC): The HMC server manages LPAR servers and lets you discover information related to VIO servers and VIO clients. You can use the virtualization management option on the Arctera InfoScale Operations Manager console to add the HMC server to Management Server.
To add the HMC server to Arctera InfoScale Operations Manager, you need to install the Control Host add-on on the host where the HMC server should be added. Virtual SCSI disks on LPAR client are supported. However, NPIV, or virtual Fibre Channel disks are not supported. Currently, only Virtual SCSI disks backed by native or DMP devices are supported. By configuring HMC server only (without the
VRTSsfmhpackage), you can discover information about the exported storage from the VIO server to the VIO clients and the devices that are given to the VIO server from the storage area network (SAN).Discovery using the
VRTSsfmhpackage that is installed on the LPAR client: The presence of theVRTSsfmhpackage on LPAR client provides additional information about them. This information is correlated with the information that is discovered using the HMC server. Virtual SCSI device discovery, and Virtual SCSI device correlation with the source device in VIO server is also supported.Note:
Arctera InfoScale Operations Manager supports only native disks as the back-end devices for the VIO server. These disks can be controlled by Microsoft Multipath I/O (MPIO) and Dynamic Multi-Pathing (DMP). Disks that are controlled by any third-party multi-pathing software (or the logical volumes), when used as the backing devices, do not have end-to-end correlation available.
Discovery using the
VRTSsfmhpackage that is installed as a part of DMP on the VIO server: When a VIO server having DMP 6.0 is added, it provides the discovery of DMP backed exported storage along with the normal managed host discovery. For end-to-end correlation, DMP 6.0 on the VIO server is required. Storage mapping for DMP backed devices is available only if the VIO server (with DMP installed) is added to Arctera InfoScale Operations Manager Management Server.Storage Insight Add-on lets you discover complete information about arrays and LUNs from the SAN, which are allocated to the VIO server.
Note:
When an array (consumed by the VIO server) is configured, or a VIO server (with DMP) is added to Arctera InfoScale Operations Manager Management Server, refreshing the corresponding HMC discovery is recommended to view the end-to-end correlation immediately in the Arctera InfoScale Operations Manager console.
