HP Integrity VM 4.3 N-Port ID Virtualization - A brief overview

hpvmdevmgmt

The hpvmdevmgmt command now lists NPIV resources as well as all the information that was previously displayed.

Example: The hpvmdevmgmt command run from the host, on which Guest1 was created, displays the following

output.

localnet:CONFIG=gdev,EXIST=YES,DEVTYPE=SWITCH,SHARE=YES::WWID_NULL

lan1:CONFIG=gdev,EXIST=YES,DEVTYPE=NIC,SHARE=NO:LSM_VS:WWID_NULL

lan0:CONFIG=gdev,EXIST=YES,DEVTYPE=NIC,SHARE=NO:vswitch1:WWID_NULL

vswitch1:CONFIG=gdev,EXIST=YES,DEVTYPE=SWITCH,SHARE=YES:guest1:WWID_NULL

/dev/rdisk/disk31:CONFIG=gdev,EXIST=YES,DEVTYPE=DISK,SHARE=NO:guest1:0x01.0x00.0x03.0x500000e01

/dev/vg_on_host/rlvol3:CONFIG=gdev,EXIST=YES,DEVTYPE=LV,SHARE=NO:guest1:HPVM_LVOL_TYPE1_0x01.0x

0x50060b00006499a8:CONFIG=gdev,EXIST=YES,SHARE=NO,DEVTYPE=NPIV,AGILE_DSF=/dev/fcd0:guest1:WWID_

NULL

/dev/fcd1:CONFIG=gdev,EXIST=YES,SHARE=YES,DEVTYPE=HBA:vwwn_0x50060b00006499b9:WWID_NULL

0x50060b00006499b9:CONFIG=gdev,EXIST=YES,SHARE=NO,DEVTYPE=NPIV,AGILE_DSF=/dev/fcd1:guest1:WWID_

NULL

NOTE:

The WWN associated with a vHBA cannot be marked as a shared resource

using the hpvmdevmgmt command.

hpvmmodify—to delete an NPIV resource

The hpvmmodify command is also used to delete a NPIV HBA from a guest.

Example:

hpvmmodify -P guest1 -d hba:avio_stor:0,4,0x50014C20000000B4,0x50014C2800000043:npiv:/dev/fcd1

NOTE:

For this operation to take effect, the guest has to be restarted.

hpvmdevinfo—show VM to host device mapping

The hpvmdevinfo command now lists NPIV resources as well as all the information that was previously displayed:

# hpvmdevinfo
