Fibre Channel Configuration
This section describes the recommended configuration that should be applied when attaching hosts to PowerStore cluster using
Fibre Channel.
NOTE: This section applies only to FC. If you are using only iSCSI with Linux, go to iSCSI HBA Configuration.
NOTE: Before proceeding, review Fibre Channel SAN Guidelines.
Pre-Requisites
When attaching a host to PowerStore cluster using Fibre Channel, the following pre-requisites need to be met:
Refer to the E-Lab Interoperability Navigator (https://elabnavigator.emc.com) for supported Fibre Channel HBA models and
drivers.
Verify all HBAs are at the supported driver, firmware and BIOS versions.
Verify all HBAs BIOS settings are configured according to E-Lab recommendations.
iSCSI Configuration
This section provides an introduction to the recommended configuration to be applied when attaching hosts to PowerStore
cluster using iSCSI.
NOTE:
This section applies only to iSCSI. If you are using only Fibre Channel with Linux and PowerStore, go to Fibre
Channel Configuration.
NOTE: Before proceeding, review the iSCSI SAN Guidelines section.
Pre-Requisites
Refer to the E-Lab Interoperability Navigator (https://elabnavigator.emc.com) for supported NIC/iSCSI HBA models and
drivers.
Configuring the PowerStore Cluster Disk Device with iSCSI
To configure the PowerStore disk device, modify the configuration file with the following parameters.
The configuration file for the multipath daemon is multipath.conf. It is used to overwrite the built-in configuration table of the
multipath daemon. When iSCSI is used with PowerStore, the iscsi.conf file is used to overwrite iSCSI specific multipathing
related settings.
To configure the PowerStore disk device, modify the /etc/iscsi/iscsid.conf file, using the following parameters:
