NOTE: When using Fibre Channel with PowerStore, the FC HBA (Host Bus Adapters) issues described in this section should be addressed for optimal performance. NOTE: Before you proceed, review Fibre Cannel and NVMe over Fibre Channel SAN Guidelines. Pre-Requisites Before installing HBAs in a Solaris host, the following pre-requisites should be met: ● Follow Oracle's recommendations for installation and setup of the appropriate HBA for your system. ● It is recommended to install the latest driver version (patch), as described on the Oracle support site for each specific FC HBA. ● Refer to the E-Lab Interoperability Navigator (https://elabnavigator.dell.com) for supported FC HBA models and drivers. Queue Depth Queue depth is the amount of SCSI commands (including I/O requests) that can be handled by a storage device at a given time. A queue depth can be set on either of the following: ● Initiator level - HBA queue depth ● LUN level - LUN queue depth The LUN queue depth setting controls the amount of outstanding I/O requests per a single path. The HBA queue depth (also referred to as execution throttle) setting controls the amount of outstanding I/O requests per HBA port. With PowerStore and Solaris, the HBA queue depth setting should retain its default value, and the initial LUN queue depth setting should be modified to 64. This is a good starting point provided good I/O response times. The specific value can be adjusted based on particular infrastructure configuration, application performance and I/O profile details. Solaris Host Parameter Settings This section describes the Solaris host parameter settings required for optimal configuration when using Dell Technologies PowerStore storage. Configuring Solaris native multipathing For a PowerStore cluster to properly function with Oracle Solaris hosts, configure the multipath settings as described in the following sections. NOTE: If the host is connected to a cluster other than PowerStore, the configuration file may include additional devices. NOTE: Currently, PowerStore clusters are only supported with native Solaris multipathing (MPxIO). Enable Solaris native multipathing on Solaris 10 and 11.0-11.4 hosts (SPARC and x86) To enable management of storage LUNs that are presented to the host with MPxIO, use the following command: # stmsboot -e NOTE: The host must be rebooted immediately after the command execution is complete. It is recommended to update all storage-related host configuration files before rebooting. 78 Host Configuration for Solaris

Pre-Requisites
Before installing HBAs in a Solaris host, the following pre-requisites should be met:
●
Follow Oracle's recommendations for installation and setup of the appropriate HBA for your system.
●
It is recommended to install the latest driver version (patch), as described on the Oracle support site for each specific FC
HBA.
●
Refer to the E-Lab Interoperability Navigator (
) for supported FC HBA models and drivers.
Queue Depth
Queue depth is the amount of SCSI commands (including I/O requests) that can be handled by a storage device at a given time.
A queue depth can be set on either of the following:
●
Initiator level - HBA queue depth
●
LUN level - LUN queue depth
The LUN queue depth setting controls the amount of outstanding I/O requests per a single path. The HBA queue depth (also
referred to as execution throttle) setting controls the amount of outstanding I/O requests per HBA port.
With PowerStore and Solaris, the HBA queue depth setting should retain its default value, and the initial LUN queue depth
setting should be modified to 64. This is a good starting point provided good I/O response times. The specific value can be
adjusted based on particular infrastructure configuration, application performance and I/O profile details.
Solaris Host Parameter Settings
This section describes the Solaris host parameter settings required for optimal configuration when using Dell Technologies
PowerStore storage.
Configuring Solaris native multipathing
For a PowerStore cluster to properly function with Oracle Solaris hosts, configure the multipath settings as described in the
following sections.
NOTE:
If the host is connected to a cluster other than PowerStore, the configuration file may include additional devices.
NOTE:
Currently, PowerStore clusters are only supported with native Solaris multipathing (MPxIO).
Enable Solaris native multipathing on Solaris 10 and 11.0-11.4 hosts (SPARC
and x86)
To enable management of storage LUNs that are presented to the host with MPxIO, use the following command:
# stmsboot -e
NOTE:
The host must be rebooted immediately after the command execution is complete. It is recommended to update all
storage-related host configuration files before rebooting.
