Enabling Multipathing Software for Solaris | Sun Microsystems 2500

7.Use the cfgadm command to configure HBA paths.

How you configure paths depends on how you are using your arrays in a SAN or direct attach environment. See the Sun StorageEdge SAN Foundation Software 4.4 Configuration Guide (www.sun.com/products-n-solutions/hardware /docs/Network_Storage_Solutions/SAN/san_software/) for information about configuring paths.

▼Enabling Multipathing Software for Solaris 10

OS

To enable multipathing software for all Fibre Channel (FC) ports on hosts running Solaris OS 10:

1.Type the following command:

# stmsboot -e

Note – See the stmsboot(1M) man page for complete details.

You are prompted to confirm the command:

WARNING: This operation will require a reboot.

Do you want to continue ? [y/n] (default: y)

2. Press Return to reboot the host.

Next Steps

After you have installed and enabled multipathing on the data hosts, configure IP addressing on the array controllers as described in Chapter 6.
