This section describes how to configure storage devices for Resource Orchestrator.
Storage Unit Configuration
When using the HBA address rename method, the VIOM server profile switchover method, the ISM profile switchover method, or the storage affinity switchover method, perform configuration of storage in advance.
When using VIOM or ISM, 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.
If storage settings (zoning, LUN masking or any other security setting) were already made for SAN, those settings should be canceled and re-defined using the server-side WWN settings chosen in "8.1.2 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).
When using the HBA address rename method or a profile switchover method, perform configuration in advance.
Access paths between servers and storage devices must be made by applying the WWPN values chosen in "8.1.2 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 "8.1.2 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
When using the storage affinity switchover method, the following settings are required.
For access paths, point-to-point WWPN zoning is required.
Zoning (or port zoning) is required for configuring access paths.
For the WWN of HBA of physical servers and the WWPN of storage devices, one-to-one host affinity configuration is required.
