Setup Guide

2. If the file is not in the expected location, run the following command to copy it from /kernel/drv:

# cp /kernel/drv/sd/conf /etc/driver/drv

3. Run the following commands to create a backup copy and modify the file:

# cp -p /etc/driver/drv/sd.conf /etc/driver/drv/sd.conf_ORIG

# vi /etc/driver/drv/sd.conf

Example

Below are the entries recommended for PowerStore storage.

sd max xfer size=0x100000;

sd-config-list = "DellEMC PowerStore", "throttle-max:64, physical-block-size:4096,

disksort:false, cache-nonvolatile:true";

nonvolatile cache

true

Post configuration steps - using the PowerStore

system

When host configuration is complete, you can access the PowerStore system from the host.

You can create, present, and manage volumes accessed from the host via PowerStore Manager, CLI, or REST API. Refer to the

PowerStore Manager Online Help, CLI Reference Guide, or REST API Reference Guide for additional information.

When adding host groups and hosts to allow Solaris hosts to access PowerStore volumes, specify Solaris as the operating

system for the newly-created hosts.

NOTE:

Setting the host’s operating system is required for optimal interoperability and stability of the host with PowerStore

storage. You can adjust the setting while the host is online and connected to the PowerStore cluster with no I/O impact.

NOTE: Refer to the PowerStore Configuring Volumes Guide for additional information.

Partition alignment in Solaris

Use Solaris format command to create partitions aligned to 4K on a PowerStore cluster LUNs for use as a raw or UFS devices.

When a PowerStore LUN is added to the ZFS pool, ZFS automatically creates aligned partitions.
