Migrating a Configuration without FC Boot
Migrating Automatically
Automatic migration provides an equivalent FC storage setup running on the Solaris FC (Leadville)
stack. Emulex's Solaris lpfc driver on the SPARC platform uses "sd" as the native SCSI driver, and works
in Solaris 2.6, 7, 8, 9 and 10. Emulex’s emlxs driver supports the Leadville stack using "ssd" as the SCSI
driver. With this procedure, a SAN setup on the host seamlessly migrates from using lpfc to the same
setup using emlxs.
Prerequisites
• SPARC server running Solaris 8, 9 or 10.
• Emulex's lpfc driver and associated application kit including HBAnyware installed on the host
system.
• Emulex's emlxs driver (SUNWemlxs) installed on the host system.
• Emulex FCode version 1.50a4 or later pre-installed on all HBAs.
Things to Know Before You Migrate
• FC tape devices do not migrate to the emlxs environment. Configure devices after migration.
• lpfc.conf parameters do not migrate into the emlxs driver environment. Note custom
configuration values before migration, as default parameters are used after migration.
Customize applicable parameters after the migration completes.
• The Leadville stack does not support LUN-level masking. Verify that the system is properly
configured to provide the same number of LUNs in emlxs as are contained in the original lpfc
environment. For a specific target, any visible LUNs that are not configured in the lpfc
environment are automatically configured into the emlxs environment.
• The Leadville stack natively supports mpxio. If you use multipathing or load balancing software,
verify that the software functions properly in the new emlxs environment.
Limitations
• If an Emulex HBA is the boot adapter, the sample script exits without proceeding with migration.
• If an Emulex HBA is configured to use the IP over FC interface, the IP interface does not migrate
to the emlxs environment.
Procedure
To automatically migrate from lpfc to emlxs:
1. Download the migrate.tar tarball file to the host system in which the lpfc driver is in control and
untar it. The tarball file contains two sample script files and a subdirectory containing binary files
that are used by the sample scripts.
2. Open the tarball file and view the start_emlxs_migration.sh and
finish_emlxs_migration.sh sample script files. Make changes to these files as needed
based upon your system configuration.
3. Login as root and run the start_emlxs_migration.sh customized script file (for details, see
page 162). After start_emlxs_migration.sh is completed, reboot the host system.
4. Login as root and change directory (cd) to where the customized migration scripts are installed.
5. Run the finish_emlxs_migration.sh customized script file (for details, see page 163).
