Veritas Volume Manager 4.1 Administrator's Guide (HP-UX 11i v3, February 2007)

Discovering and Configuring Newly Added Disk Devices
64 VERITAS Volume Manager Administrator’s Guide
The next command discovers devices that are connected to the specified physical
controller:
# vxdisk scandisks pctlr=8/12.8.0.255.0
Note The items in a list of physical controllers are separated by + characters.
You can use the command vxdmpadm getctlr all to obtain a list of physical
controllers.
You can specify only one selection argument to the vxdisk scandisks command.
Specifying multiple options results in an error.
For more information, see the vxdisk(1M) manual page.
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 toan HP-UXsystem 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 (see “Administering Dynamic Multipathing (DMP)” on
page 101) 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” on page 68.
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.
Adding Support for a New Disk Array
The following example illustrates how to add support for a new disk array named
vrtsda to an HP-UXsystem using a vendor-supplied package on a mounted CD-ROM:
# swinstall -s /cdrom vrtsda
