With the V4.3 January 2012 patch release installed, NPIV can have the following configuration
limits:
Table 3 NPIV Configuration Limits
LimitsDescription
8NPIV HBAs per guest
8NPIV HBAs per physical HBA
2048Lunpaths per NPIV HBA
8Lunpaths per NPIV LUN
2048LUNs per NPIV HBA
2048NPIV LUNs per guest
16384Lunpaths per guest
Integrity VM V4.3 supports the use of NPIV with the following dependencies:
• Host:
◦ HP-UX 11i v3 March 2011 Fusion OE or HP-UX 11i v3 September 2011 Fusion OE
◦ FCD driver from HP-UX 11i v3 September 2011 Fusion OE
◦ HostAVIOStor B.11.31.1201
• Guest:
◦ HP-UX 11i v3 March 2010 through September 2011 Fusion OE
◦ GuestAVIOStor B.11.31.1201
8.1.2 Adding NPIV HBAs to Existing Guest with AVIO Storage HBAs May Cause a
Problem
When adding NPIV HBAs to an existing guest that has AVIO storage HBAs, the next boot of the
guest may panic with the message “panic: GVSD: Unable to allocate iocb during
initialization”, due to the known defect.
To work around this problem, reduce the number of AVIO storage HBAs by consolidating LUNs
into fewer AVIO storage HBAs. AVIO allows up to 128 AVIO LUNs under 1 AVIO HBA. The
following example, shows how to consolidate 20 AVIO LUNs from 20 AVIO HBAs to 1 AVIO
HBA:
1. Check status, device info, and perform an ioscan. Notice that the example begins with 20
AVIO LUNs under 20 AVIO HBAs:
