HP-UX vPars and Integrity VM V6.3 Administrator Guide

A Troubleshooting
A.1 Creating VMs
A.1.1 Configuration error on starting the VM
When you start the VM, the following message is displayed:
Configuration error: Device does not show up in guest.
If this is observed:
• Verify that the path name to the file-backing store is correct and that the physical storage
device is mounted.
• Verify that the size of the physical storage device is divisible by 512 bytes (for a disk device)
or 2048 (for a DVD device).
• Modify the VM to use correct file-backing store path name and size, using the hpvmmodify
command.
A.2 Storage
A.2.1 Attachable storage devices
Storage devices are not seen in guest
Use the ioscan command and check that the devices are connected and claimed by VSP. Install
any device special files for new devices, if required.
The following is an example of a claimed tape device:
# ioscan -m lun/dev/rtape/tape1_BEST
Class I Lun H/W Path Driver S/W State H/W Type Health Description
==============================================================================
Tape 1 64000/0xfa00/0x0 estape CLAIMED DEVICE online STK T9940B

/dev/rtape/tape1_BEST/dev/rtape/tape1_BESTn
/dev/rtape/tape1_BESTb/dev/rtape/tape1_BESTnb
The following is an example of an unclaimed media changer device:
# ioscan —fk
Class I H/W Path Driver S/W State H/W Type Description
======= === ======== ====== ========== ========= ==============
ext_bus 6 0/2/1/0 c8xx CLAIMED INTERFACE SCSI C1010 Ultra0 Wide LVD A6828-60101
target 35 0/2/1/0.0 tgt CLAIMED DEVICE
unknown -1 0/2/1/0.0.0 UNCLAIMED UNKNOWN HP ThinStor AutoLdr
If the device is not seen, there is a hardware problem or AVIO ID conflict. See the documentation
for the particular device to resolve this issue before proceeding.
If the device is seen but not claimed, this is a result of missing drivers in the VSP. Integrity VM does
not require the drivers to be loaded on the VSP for the devices to be attached. The HP-UX tape
(stape and estape) and changer (schgr and eschgr) drivers are not loaded by default unless
those devices are connected at install time. To load the drivers, use the kcmodule command to
statically load the drivers. To complete the installation, the VSP must be rebooted. Any guests that
are running must be shut down before loading these drivers.
The following is an example of installing the tape driver:
# kcmodule stape=static
The following is an example of installing the media changer driver:
# kcmodule schgr=static
