7.1.4 Enabling VERITAS DMP
To enable VERITAS Dynamic Multi-Pathing (DMP) support on VERITAS Volume
Manager in the Solaris operating system, 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.
Note –
JBOD arrays require a license from VERITAS to enable any of its advanced
features. Refer to VERITAS Volume Manager Release Notes or contact VERITAS
Software Corporation for licensing terms and information.
