Greetings all,
Has anyone worked with HPVM? I have a new system here (Tuckwila based bl870)
and I'm trying to set up a couple of VM with IVM.
Firstly- the host system has a 2T lun attached to it and is using MPIO,
ioscan -m dsf shows:
# ioscan -m dsf
Persistent DSF Legacy DSF(s)
========================================
/dev/rdisk/disk4 /dev/rdsk/c0t8d0
/dev/rdisk/disk5 /dev/rdsk/c0t8d1
/dev/rdisk/disk6 /dev/rdsk/c1t8d0
/dev/rdisk/disk7 /dev/rdsk/c1t8d1
/dev/rdisk/disk7_p1 /dev/rdsk/c1t8d1s1
/dev/rdisk/disk7_p2 /dev/rdsk/c1t8d1s2
/dev/rdisk/disk7_p3 /dev/rdsk/c1t8d1s3
/dev/rdisk/disk9 /dev/rdsk/c2t0d0
/dev/rdisk/disk18 /dev/rdsk/c6t3d0
/dev/rdsk/c5t3d0
/dev/rdsk/c3t3d0
/dev/rdsk/c4t3d0
/dev/rdsk/c10t3d0
/dev/rdsk/c7t3d0
/dev/rdsk/c8t3d0
/dev/rdsk/c9t3d0
You can see that disk18 is the MPIO device for all the paths.
Secondly- I want to use AVIO on the guest system for performance. For
maximum performance, it is recommended to use one AViO device per vCPU, in
this case, I need 6 AVIO devices. OK:
# hpvmmodify -P ptsshpdb01 -a disk:avio_stor:1,0,0:disk:/dev/rdisk/disk18
# hpvmmodify -P ptsshpdb01 -a disk:avio_stor:1,1,0:disk:/dev/rdisk/disk18
hpvmmodify: ERROR (ptsshpdb01): Duplicate backing device
'/dev/rdisk/disk18'.
hpvmmodify: ERROR (ptsshpdb01): Unable to add device '/dev/rdisk/disk18'.
hpvmmodify: Unable to create device
disk:avio_stor:1,1,0:disk:/dev/rdisk/disk18.
hpvmmodify: Unable to modify the guest.
You see that the first device is created just fine, but fails in subsequent
attempts.
Has anyone worked with this before? It is also recommend NOT to use DMP in
the guest, because the guest does not know the I/O of other guests and
cannot balance appropriately.
Thanks in advance
-yce
