HP vPars and Integrity Virtual Machines V6.1 Administrator Guide

# ioscan -Nfun
The following is an example of a claimed tape device:
tape 1 64000/0xfa00/0x19 estape CLAIMED DEVICE HP Ultrium 1-SCSI
/dev/rtape/tape1_BEST /dev/rtape/tape1_BESTn
/dev/rtape/BESTb /dev/rtape/tape1_BESTnb
If the device is not seen in ioscan -fun, proceed to step 2c. Otherwise, go to step 3.
c. If the device is not claimed, make sure the device is seen:
# ioscan -fk
The following is an example of an unclaimed media changer device:
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. Consult 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 changer (schgr) 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
If you are not loading the VSP drivers, proceed to step 4.
If you are loading the VSP drivers, the devices should show up in ioscan with device files
after the VSP reboot. In which case, proceed to step 3.
3. Install esctl device files using the hpvmdevmgmt command. For example:
# hpvmdevmgmt -I
4. Locate the passthrough device file that corresponds to the device slated for attachment.
The following are examples of a tape device:
Agile = /dev/rtape/tape1_BEST
ESCTL = /dev/pt/pt_tape1
The following are examples of media changer device:
Agile = /dev/rchgr/autoch1
ESCTL = /dev/pt/pt_autoch1
The following are examples of CD/DVD burner device:
Agile = /dev/rdisk/disk7
ESCTL = /dev/pt/pt_disk7
Attached devices cannot be shared simultaneously across active vPars/VMs. Only one active
vPar/VM can be given a particular attached device at a time. However, like virtual devices,
attached devices can be attached and detached dynamically across active vPars/VMs (see
Section 9.3 (page 133)). Also, as the device is being attached to a vPar/VM, it cannot be opened
by the VSP at the time of or during attachment.
