After discovering the WWNs of the host adapters and connecting the storage system to the host, you need to configure the new hosts and new LU paths on the storage system.
- Register the new hosts in host groups/iSCSI targets. For details, see the Provisioning Guide for the storage system.
When registering hosts in multiple host groups, set the security switch (LUN security) to enabled, and then specify the WWN of the host adapter.
- Configure the LU paths for the newly attached storage devices, including defining primary LU paths and alternate LU paths and setting the UUID. For details, see the Provisioning Guide for the storage system. Note: Hitachi multipathing best practice is Single-Initiator Single-Targets configuration in which each HBA has only one path to the same LU. For example, you can provide four paths to each LU if you have four HBAs. For details, contact customer support.
- Set Fibre Channel authentication as needed on host groups, ports, and fabric switches of the storage system. For details, see the Provisioning Guide for the storage system.
For details about iSCSI network configuration (for example, registering hosts in iSCSI targets, adding CHAP users, defining LU paths), see the Provisioning Guide for the storage system.
