Compatibility Information and Installation Requirements

Chapter 134

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, the VERITAS Volume

Manager does not provide multipathing support.

NOTE 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.

Other Requirements

During vxinstall, it is advisable to have at least two disks (preferably on separate

controllers) in the default VxVM disk group, rootdg. Having at least two disks guarantees

that multiple copies of the VxVM configuration database exist. This database is required not

only to start VxVM, but also required when making VxVM configuration changes (for

example, creating volumes).

NOTE Despite its name, rootdg will not be your root disk.
