S
b. Format 2: Defining 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.
NOTE:
Do not create EIOC names with similar character strings (e.g.,
eioc3 and eioc30). There is a limitation with certain Linux
operating systems that cannot recognize the subtle differences.
The result is that the user will be unable to ping across the
network.
NOTE:
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.
