Overview

AVIO

The Integrity VM v3.5 release introduced new accelerated storage and networking products to improve the overall I/O performance for Integrity VM. The Integrity VM v4.0 release extends the support for AVIO to HP-UX 11i v3 based hosts. These new Accelerated Virtual I/O (AVIO) products provide up to a 60% reduction in service demand and as much as twofold improvement in throughput over the existing fully virtualized storage and networking Integrity VM solutions.

The AVIO LAN and Storage technology consists of two components, an Integrity VM Host component (HostAvioLan / HostAVIOStor) and an Integrity VM Guest component (GuestAvioLan / GuestAVIOStor). A user must install and configure the respective kernel drivers on the VM Host and Guest systems for the complete AVIO LAN/Storage functionality.

Customers using HP-UX Virtual Partitions v6.0 or Integrity VM v4.30 and v4.2x release should install the October 2013 AVIO web release (B.11.31.1211.01).

Note:

-          AVIO B.11.31.1211.01 version bundles are not supported on OE later to 1109

-          Do not install AVIO B.11.31.1211.01 version bundles on HP-UX vPars & Integrity VM v6.1 and later versions.

  • QXCR1001302005 : Some of the memory arenas created by HVSD and GVSD had incorrect attributes set.

 

  • QXCR1001302009 : Guests with high I/O load may hang during interrupt migrations running in the guest

 

  • QXCR1001302011 : Very frequent interrupt migrations in the guest may result in a guest hang

 

  • QXCR1001302012 : Incorrect LUN ID printed in following warning message when host does a forced reset:

HPEVM reset this host because a disk write timed out long
after it should have been completed by the host (40 seconds)
and the guest that initiated it has terminated.
Resetting the host is necessary to ensure the disk can now
be accessed by another cluster node without risking data
corruption. This condition should not have occurred.
Please report it to Hewlett-Packard Enterprise.

Additional information:

 

  1. Steps to follow while migration of a guest HBA between VIO and AVIO. This is to ensure that agile disk device files under the migrated HBA remains the same.

 

o   Boot the guest with GuestAVIOStor 11.31.0810 or higher depot. This step is required even if you do not have any AVIO devices configured.

o   Shutdown the guest gracefully using the "shutdown (1m)" commands.

o   Migrate the HBA from VIO to AVIO (or vice-versa) using hpvmmodify command.

o   Boot the guest up and verify that all the agile device files are as expected.

 

 

Known issues

 AVIO Storage:

1.   Executables terminating with SIGILL error when using logical volumes created from an iSCSI disk.

 

There is a known issue of having stale instruction cache entries when a logical

 volume created out of an  iSCSI disk, is presented as a backing store to the

guest. This will result in executables from this backing store randomly dumping

core with an illegal instruction error. So this configuration is not supported.

 

2.    Warning message in syslog during installation or update of Integrity VM and HostAVIOStor

Symptoms:
During the installation or update of Integrity VM along with the HostAVIOStor product, the following warning message may be seen in the /var/adm/syslog/syslog.log:

WARNING: mod_uninstall: Attempt to uninstall hvsd module: Module is not installed

Fix/Workaround:
The above warning message can be safely ignored. They do not indicate any problem with the installation or update.
