NOTE: Refer to your operating system documentation for general boot from SAN configuration.
NOTE: The current PowerStore version does not support mapping individual LUNs to host under host group.
Follow these guidelines when configuring boot from SAN:
● Prior to the installation on a PowerStore LUN, the host must have been manually registered on the system and assigned to a
Storage Group.
○ At least one LUN must be bound to the host's Volume Group and owned by the node connected to the HBA being used
for the fabric boot.
○ The lowest-numbered path to the boot LUN must be the active path.
● It is recommended that the boot LUN be assigned Host LUN ID 0. During the installation procedure, it is recommended that
only one LUN be mapped to a host for ease of use.
○ Once the installation has completed, additional LUNs may be mapped to the host.
Follow these guidelines for clustered boot from SAN mapping:
● For every physical host there should be one host in the PowerStore manager. Do not create a host group.
● Boot LUNs will be mapped only for the specific host.
● Shared LUNs will be mapped to all hosts in the cluster. The user must keep the same LUN ID across the cluster for shared
LUNs.
