Format 2: Define an IOC using the IOCSTRING. Defining the IOC 
using the IOCSTRING allows VIO hardware to be hot-swapped in and 
out of a specific slot. The host attempts to connect to the specified IOC 
(1, 2, or 3) on the VIO hardware that currently resides in the specified 
slot of the specified chassis. Use the following format to allow the host 
to connect to a VIO hardware that resides in a specific slot of a specific 
chassis:

{CREATE;
NAME="eioc1";
IOCSTRING="Chassis 0x00066A0005000001, Slot 1, IOC 1";
RX_CSUM=TRUE;
HEARTBEAT=100; }

Each CREATE block must specify a unique NAME. The NAME 
represents the Ethernet interface name that will be registered with the 
Linux operating system.

c.

Format 3: Start VNIC using DGID. Following is an example of a DGID 
and IOCGUID VNIC configuration. This configuration allows for the 
quickest start up of VNIC service:

{CREATE; NAME="eioc1";
DGID=0xfe8000000000000000066a0258000001;IOCGUID=0x66a0130
000001;
}

This example uses DGID, IOCGUID, and IOCSTRING:

{CREATE; NAME="eioc1";
DGID=0xfe8000000000000000066a0258000001;
IOCGUID=0x66a0130000001;
IOCSTRING="Chassis 0x00066A00010003F2, Slot 1, IOC 1";
}

The IOCSTRING field is a literal, case-sensitive string. Its syntax 
must be exactly in the format shown in the previous example, 
including the placement of commas. To reduce the likelihood of 
syntax error, use the command 

ib_qlgc_vnic_query

 -es. 

Note that the chassis serial number must match the chassis Ox 
(hex) value. The slot serial number is specific to the line card as 
well.
