HP Integrity Virtual Machines 4.3: Installation, Configuration, Administration

PciBus•
• PciDev
• Addr (Target Id)
Addr (Target Id) is encoded as an HP-UX tgt ID and an HP-UX lun ID in the HP-UX hardware
path.
HP-UX tgt ID and HP-UX lun ID are calculated from Addr (Target Id) in the hpvmstatus
display using the following equations:
HP-UX tgt ID = Addr(Target Id) % 16
HP-UX lun ID = Addr(Target Id) / 16
Note the following example:
# ioscan -fne

In this example, exp1 / exp2 represents the quotient from exp1 divided by exp2 (integer
division), and exp1 % exp2 finds modulo of exp1 divided by exp2 (that is, finds the remainder
of an integer division).
2. get_info option of the gvsdmgr utility
If you are using the HP-UX DSF, the following gvsdmgr option can be used to get the VSD
LUN ID, which is the same as the Addr (Target Id) in the hpvmstatus display. The gvsdmgr
utility displays VSD LUN Id as a hexidecimal number. The first nibble of VSD LUN Id
becomes HP-UX lun ID, and the second nibble becomes HP-UX tgt ID.
The following example shows the get_info option with the gvdsmgr utility:
# gvsdmgr get_info -D /dev/gvsd0 -q lun=/dev/rdsk/c0t6d1

Lun DSF : /dev/rdsk/c0t6d1
VSD LUN Id : 0x16
Lun Hardware path : 0/0/2/0.6.1
LUN State : UNOPENED
The following is a method for mapping an Integrity VM HP-UX 11i v3 guest hardware path or
HP-UX 11i v3 DSF to an Integrity VM Host hpvmstatus display using the ioscan utility:
# ioscan -m dsf /dev/rdsk/c0t6d1
