3 Issues in this release
This chapter contains notes about creating and configuring virtual machines on the VSP system.
3.1 Changes and Issues in this Release
This section describes new information and issues in this release.
3.1.1 hpvmhwmgmt might add ports in link aggregates into the DIO pool
The hpvmhwmgmt command might put a port used by a link aggregate into the direct I/O (DIO)
networking pool. A LAN interface cannot be used by both APA and DIO at the same time. Before
adding a LAN interface into the DIO pool, make sure that it is not being used by an APA interface.
To find out whether a DIO capable lan device is being used in a link aggregate, use the ioscan
and nwmgr commands. For example, add 0/0/0/9/0/0/0 into the DIO pool, a DLA device with
0/0/0/9/0/0/1 as its other sibling, and check whether both of these are being used by a link
aggregate:
1. Use ioscan to find the instance numbers of these lan interfaces:
# ioscan –kfnC lan
lan 16 0/0/0/9/0/0/0 iexgbe CLAIMED INTERFACE HP 454521-002E PCIe 2-p …
lan 17 0/0/0/9/0/0/1 iexgbe CLAIMED INTERFACE HP 454521-002E PCIe 2-p …
Now the interfaces are PPAs 16 and 17.
2. Use nwmgr to see whether lan16 and lan17 are being used by a link aggregate. If you see
lan9XX in the “Related Interface” column for the lan interface in which you are interested, then
it is being used by APA:
# nwmgr
Name/ Interface Station Sub- Interface Related

lan0 UP 0x78ACC089BF02 iexgbe 10GBASE-KR
…
lan7 DOWN 0x78ACC089BF09 iexgbe 10GBASE-KR
lan16 UP 0x68B599B54220 iexgbe 10GBASE-KR lan901
lan17 DOWN 0x68B599B54224 iexgbe 10GBASE-KR
..
lan900 DOWN 0x000000000000 hp_apa hp_apa
lan901 UP 0x68B599B54220 hp_apa hp_apa
lan902 DOWN 0x000000000000 hp_apa hp_apa
lan903 DOWN 0x000000000000 hp_apa hp_apa
lan904 DOWN 0x000000000000 hp_apa hp_apa
#
In this case, lan16 is being used by APA interface lan901, but not lan17.
3.1.2 Analyzing failures when DIO resources in use by the VSP
If hpvmhwmgmt -p dio -a hwpath fails due to a resource being in use by the VSP, check the
/var/adm/cra.log file for additional information on the resources in use by the VSP. The
following example shows the type of error you might see in this case:
system# hpvmhwmgmt -p dio -a 0/0/0/4/0/0/0
hpvmhwmgmt: ERROR - Resources for: '0/0/0/4/0/0/0' are in use by your host.
hpvmhwmgmt: ERROR - could not reserve hwpath: '0/0/0/4/0/0/0' for DIO.
hpvmhwmgmt: ERROR - failed to reserve and store hw path: '0/0/0/4/0/0/0' for DIO.
hpvmhwmgmt: Unable to manage dio pool resource.
