Host modes
The following table lists the host modes that are available on the VSP G200, G400, G600, G800 or VSP F400, F600, F800 storage system. Carefully review and determine which host modes you will need to use when configuring your system and observe the cautions about using certain host modes. Host modes and host mode options must be set on the port before the host is connected. If you change host modes or host mode options after the host is connected, the host (server) will not recognize it.

21 VMware Extension |
When registering VMware server hosts. If the virtual host on VMware recognizes LUs by the Raw Device Mapping (RDM) method, set the host mode related to OS of the virtual host. Example: If a LUN/LDEV is formatted as VMFS (where virtual machines and their VMDK’s usually reside), it should be set with HMO 21. However, if a LUN/LDEV is formatted as a specific file system format (for example, NTFS) and has application requirements to be presented directly to a virtual machine as an RDM, it should be set to the HMO specific to that OS/filesystem (e.g., such as HMO 2C for Windows). A common example of VM’s with this mix would be: C: drive – OS VMDK on VMFS D: drive – RDM for application data In this example, 2 different Host Groups should be created for a single host with different HMO and LUN’s assigned. |
