Using HPVM 3.5 -adding another disk device

Tom Haddad — Fri, 13 Apr 2012 13:25:08 GMT

I have one guest where i have 10 devices 0,0,0 thru 0,0,9 assigned and 15 more with 0,1.0 thru 0,1,14.

0,1,x controller is maxd' at 15 devices but I can add another devices at 0.0,10 right?

I know thet total number that a guest can have is 30 devices. Im getting close!

Command would be...

hpvmodify -p vmguest -a disk:scsi:0,0,10:disk:/dev/dsk/cxtxdx

From manual:

A VM Host administrator specifies this SCSI MPT adapter using the following:

device :scsi:pcibus ,pcislot ,scsitgt

where:
• device is one of the following: disk, dvd, tape, changer, or burner
• pcibus is an integer from 0-6.

The virtual AVIO and MPT adapters are supported only on PCI buses 0-7.

• pcislot is an integer from 0-7.

A PCI function number is not specified. It is implicitly zero because the virtual MPT storage
adapter supports only a single channel.

• scsitgt is an integer from 0-14 for virtual SCSI (15 is reserved for the virtual SCSI adapter)
and 0–127 for AVIO. All supported storage device types can share the same virtual SCSI
MPT or AVIO adapter by specifying the same PCI bus and slot numbers. A virtual SCSI
MPT or AVIO adapter can be added only to a virtual machine if it has a device connected
to it.

But you can also do

hpvmodify -p vmguest -a disk:scsi::disk:/dev/dsk/cxtxdx

Thanks.. I understand the SCSI MPT, etc.

At pcislot 1 all 15 slots are in use (0-14) but only using 0-9 assigned to controller 0.

(see hpvmstatus below...)

Im code the values (pcibus, pcislot, scsitgt) in the hpvmodify. I want to assign the next device with the command I specified earlier in the post (to 0,0.10)
