If the vxdmpadm disable ctlr= ctlr_name command is used for the above
configurations to disable I/O through a particular controller, I/O can be stopped through
paths that were not intended by the user.
If each FC10 disk system is individually connected to the host (using separate HBAs),
the above mentioned feature functions correctly and as expected.
DMP and JBOD Support
The Dynamic Multipathing feature on JBOD drives works only if the individual disks
provide unique serial number information. If the individual disks do not provide unique
serial numbers, even if the disks are configured for multipathing in hardware, VxVM
does not provide multipathing support.
HP is continually adding support for additional hardware and software. Contact your HP
Service Representative for information about additional support or refer to the latest
edition of these Release Notes on http://docs.hp.com.
