6-54 Sun StorEdge 3000 Family Installation, Operation, and Service Manual • May 2004
6.3.1 Other Supported Software
Multipathing for the Sun StorEdge 3510 and 3511 FC arrays is provided by Sun
StorEdge Traffic Manager software. Multipathing software is required when you
have multiple connections from a server to an array (directly or through a switch),
want to avoid a single point of failure, and are setting up a configuration with
redundant pathing. Multipathing software makes multiple paths between the server
and the storage system and provides full services on each path for path failover.
Refer to the appendix for your host and to the release notes for your array for
information about which versions of Sun StorEdge Traffic Manager software are
supported on your platform.
For information about additional supported or provided software, also refer to the
release notes for your array.
6.3.2 Enabling VERITAS DMP
To enable VERITAS Dynamic Multi-Pathing (DMP) support on VERITAS Volume
Manager in the Solaris operating environment, perform the following steps.
Note – To see instructions for enabling VERITAS DMP on other supported
platforms, refer to your VERITAS user documentation.
1. Configure at least two channels as host channels (channels 1 and 3 by default) and
add additional host IDs, if needed.
2. Connect host cables to the I/O host ports configured in Step 1.
3. Map each LUN to two host channels to provide dual-pathed LUNs.
4. Add the correct string to vxddladm so VxVM can manage the LUNs as a
multipathed JBOD.
5. Reboot the hosts. System reboot is required to implement these changes.
