Veritas Volume Manager 5.0 Administrator's Guide (September 2006)

82 Administering disks
Discovering and configuring newly added disk devices
partial device discovery. For example, this command makes VxVM discover newly added
devices that were unknown to it earlier:
# vxdisk scandisks new
The next example discovers fabric devices:
# vxdisk scandisks fabric
The following command scans for the devices c1t1d0 and c2t2d0:
# vxdisk scandisks device=c1t1d0,c2t2d0
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 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 121) 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 86.
