How to install Integrity VM Guest using Host USB DVD drive

Abstract

This article explains the limitations of using USB DVD drives on Integrity Virtual Machine Guests. This information applies to systems that uses USB DVD inserts instead of [SCSI | IDE interfaces], like the rx2660, rx3600 and rx6600. This also applies to blade systems like the BL860C and BL870C when using an external USB drive instead of the Blade enclosure vMedia software.

Background

Integrity Virtual Machines 3.5 and 4.0 only support USB DVD of this platforms as virtual disks, in other words, the HPVM guest will detect all it's virtual CD/DVD as USB units, but USB units in the host cannot be used as backing store for HPVM guest, only the use of ISO files is supported on this situation. Direct attachment of the USB device is not supported, in most cases yields sub standard performance and I/O errors on the HPVM guest are common (this I/O errors are actually time outs on the HPVM host USB subsystem.

The same procedures detailed here can be use to present [SCSI | IDE] DVD/CD drives to HPVM guests.

Identify USB DVD/CD devices

On HP-UX 11i v2 and 11i v3 Hosts, before the Update to USB Driver Support made on late December 2008, USB 2.0 transfer speed was not supported. On HP-UX 11i v3 Update 3 and below, agile device special files (/dev/disk/disk#) for USB DVD/CD was not available. The following ioscan commands can be used to identified the USB DVD special device file.

The following commands can be used to identified the DVD/CD special device files on each platform.

HPUX 11i v2:

# ioscan -fnk

                               /dev/dsk/c0t0d0   /dev/rdsk/c0t0d0
...

Note that on HP-UX 11i v2 prior to the Update to USB Driver Support, the USV DVD/CD devices Hardware Path will be attached to a USB OHCI Interface using the 00 USB Class driver through a UsbScsiAdaptor.

                           /dev/deviceFileSystem/Usb/MassStorage/rdsk/disk@UnknownDevice-1659+9479=00

Is highly recommended to schedule downtime of the HPVM host to installing the USB Driver Support updates detailed on the following guides:

This updates will provided USB 2.0 transfer speeds and provides agile device special files to HP-UX 11i v3 systems. Other well know USB stack performance problem are also corrected with this update dependencies. Check the previous guides for complete details.

Assign Host USB DVD to the HPVM guest

There are two methods to use USB dvd drives to provided HPVM guest backing storage:

  1. Create (dump) ISO images from the installation media
  2. Assign the Host USB DVD to the Guest

The supported method is to create a ISO image of the bootable HP-UX installation media. The unsupported method is to present USB drive directly to the HPVM guest with the Update to USB Driver Support patches installed on the HPVM host. This second approach is not widely tested, and some glitches are expected.

Following are the details for each method.

Create ISO images from the installation media

1. Copy the content of the installation media from the USB drive. The /var/tmp directory is used through the example, but using the same convention directory convention (/var/opt/hpvm/ISO-images of the Linux ISO images, chapter 6.2 of the Administration Guide) is highly recomended.

# mkdir /var/tmp/iso

HPUX 11i v2

# dd if=/dev/rdsk/c#t#d# of=/var/tmp/iso/B.11.31.ISO bs=2048

HP-UX 11i v3

  • On systems without the Update to USB Driver Support patches:
# dd if=/dev/deviceFileSystem/Usb/MassStorage/rdsk/disk@UnknownDevice-1659+9479=00 \
of=/var/tmp/iso/B.11.31.ISO bs=2048
  • On systems with Update to USB Driver Support patches:
# dd if=/dev/rdisk/disk# of=/var/tmp/iso/B.11.31.ISO bs=2048
NOTE: Even while using USB 2.0 transfer speeds, copying the disk using the HP-UX dd command can take a long time. You can use other speciality tools that allows the creation of CD/DVD ISO images on your worstation. On Windows based systems, the opensource imgburner has been tested.


2. Assign the ISO image to the HPVM guest.

# hpvmmodify -P tifa -a dvd:scsi::file:/var/tmp/iso/B.11.31.ISO

3. Verify the status

# hpvmstatus -P tifa

How to quickly mount an USB DVD | CDROM

1. Edit /etc/fstab and add a mount entry for the USB device special file.

...
/dev/deviceFileSystem/Usb/MassStorage/dsk/disk@UnknownDevice-1659+9479=00 /usbcd cdfs rr 0 2

2. Create the mount point directory

# mkdir /usbcd

3. Mount the the USB DVD | CDROM

# mount /usbcd


How to swap DVD images online

If the HPVM Host administrator sets up multiple Virtual FileDVD images for the HPVM guest, the HPVM Virtual Console command eject and insert media should be used to select among the available ISO files assigned to the guest. The eject command changes the Virtual FileDVD into a Virtual NullDVD device.

ISO files can be added to or removed from the file system directory for the Virtual FileDVD by the HPVM Host Administrator. Once this ISO file directory is updated, use an insert command to view all the newly available ISO files in the directory and to choose one to be used for a new Virtual FileDVD. It is not necessary to change the file directory between each eject and insert operation. The guest administrator can change the ISO files provided in the file directory without any HPVM Host Administrator interaction.

Example:

Note that all the process is accomplish from the HPVM guest.


1. Current Virtual FileDVD status.

# diskinfo /dev/rdsk/c1t7d0
