Discovering and configuring newly added disk devices

Alternatively, you can specify a ! prefix character to indicate that you want to scan for all devices except those that are listed:

#vxdisk scandisks !device=c1t1d0,c2t2d0

You can also scan for devices that are connected (or not connected) to a list of logical or physical controllers. For example, this command discovers and configures all devices except those that are connected to the specified logical controllers:

#vxdisk scandisks !ctlr=c1,c2

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 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 (see “Administering dynamic multipathing (DMP)” on page 125) 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 87.

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.
