This section describes how to configure storage devices for Resource Coordinator VE.
Storage Device Settings
Using the HBA address rename function or VIOM requires adequate preparation of storage environment settings (as described below).
When using VIOM, configure storage devices according to the WWN assigned to each server.
SAN storage settings can be configured using storage management software (such as ETERNUSmgr, ETERNUS SF Storage Cruiser or others). For details, refer to the manual of the relevant product.
The storage settings mentioned here are those that apply to the servers to be managed with I/O virtualization. If storage settings (zoning, LUN masking or any other security setting) were already made for SAN, those settings should be cancelled and re-defined using the server-side WWPN settings chosen in "3.3.2 HBA and Storage Device Settings".
The logical volumes for storage devices and affinity groups allocated for servers must be configured.
These settings can be configured easily using either storage management software (such as ETERNUSmgr or the Storage Volume Configuration Navigator feature of ETERNUS SF Storage Cruiser).
Access paths between servers and storage devices must be made by applying the WWPN values chosen in "3.3.2 HBA and Storage Device Settings" to each server HBA. This will allow servers to access storage devices.
To configure storage devices and Fibre Channel switches on SAN, use the appropriate storage management software.
Note that these configurations are best performed using the ETERNUS SF Storage Cruiser's storageadm zone command.
Using the ETERNUS SF Storage Cruiser's storageadm zone command for SAN settings
After registering the storage for management in the ETERNUS SF Storage Cruiser manager, set up access paths using the "add" parameter of the storageadm zone command, based on the storage-side designs that were chosen in "3.3.2 HBA and Storage Device Settings". The WWPN of the target storage device CA port must be specified with the storageadm zone command.
As it is necessary to specify the WWPN of the CA port of the relevant storage, do so using either storage management software (such as ETERNUSmgr) or ETERNUS SF Storage Cruiser after the storage device has been configured.
Refer to the ETERNUS SF Storage Cruiser manual for details on the storageadm zone command, configurable storage devices, and the graphical interface used to check access path settings.
Note
For access paths, point-to-point WWPN zoning is required.
Zoning (or port zoning) is required for configuring access paths.
