Discovering disks and dynamically adding disk arrays

You can dynamically add support for a new type of disk array which has been developed by a third-party vendor. The support comes in the form of vendor-supplied libraries, and is added to an HP-UX system by using the swinstall command.

Disk categories

Disk arrays that have been certified for use with Veritas Volume Manager are supported by an array support library (ASL), and are categorized by the vendor ID string that is returned by the disks (for example, "HITACHI").

Disks in JBODs for which DMP can be supported in Active/Active mode, and which are capable of being multipathed, are placed in the DISKS category.

Disks in unsupported arrays can be placed in this category by following the steps given in Adding unsupported disk arrays to the DISKS category.

Disks in JBODs that do not fall into any supported category, and which are not capable of being multipathed by DMP are placed in the OTHER_DISKS category.
