View the hwmgr and dsfmgr man pages for more information on using these
commands.
If you are unable to access the virtual disk, check the following:
■ Verify all cabling to the switch, Enterprise Virtual Array, and host.
■ Verify all firmware levels (check the Enterprise Virtual Array QuickSpecs and
associated release notes for details).
■ Ensure you are running a supported version of the host operating system (see
the release notes included with this kit).
■ Ensure that the correct host is selected for this virtual disk and that a unique
OS Unit ID is used in the Command View EVA.
■ Ensure Tru64 UNIX is selected as the operating system for the virtual disk in
the Command View EVA.
Configuring Virtual Disks from the Host
After you have set up the virtual disks on the Enterprise Virtual Array and have
rescanned or restarted the host, you need to follow the host-specific conventions
for configuring these new disk resources. These disk resources then become
usable just like any other disk resource to the host system. Refer to the
documentation that came with your server for specific instructions on setting up
disk resources.
Tru64 UNIX treats an HSV110 virtual disk much like a SCSI disk; therefore, to
prepare your virtual disk for access by the Tru64 UNIX file system, you must do
the following:
■ Create a file system on the virtual disk.
■ Mount the file system (to gain access to the virtual disk).
Creating Partitions on a Virtual Disk Using disklabel
Create the partitions on a virtual disk by issuing a disklabel command. The
disklabel command partitions the virtual disk for access by Tru64 UNIX.
Tru64 UNIX defines only partitions a, b, c, and g for the HSV110 controller. In
addition, refer to the rz and disktab man pages for more information about the
disklabel utility.
