4.7 Zoning
Note:
If multiple devices share a serial number, the devices represent either
multiple HBAs within the host or multiple IOMs within the enclosure. In either
situation, any of the listed device paths can be used to send the binary file
to the enclosure.
Step 3 :
Use the
sg_ses_microcode
utility to send the binary file (either
Disable_Config.bin
or
Clear_Config.bin
) to the enclosure through any of the IOM SEP handles:
# sg_ses_microcode /dev/sg1 -m0xe -b 4096 -N -I H4102-
J_Zoning_Clear_Config.bin
Note:
In this example, the
Clear_Config.bin
file is being used.
Step 4 :
Use the
sg_ses_microcode
utility to activate the file:
# sg_ses_microcode /dev/sg1 -m0xf
After the file is activated, the SAS connectors will be cycled off and on, triggering the host to
perform discovery.
Note:
Depending on which binary file was used, either zoning is now disabled or the
file-based zoning feature itself is now disabled. The remaining steps in this task are for
verification purposes and require the WDDCS Tool. For instructions on disabling file-based
zoning using
only
the WDDCS Tool, please see the
WDDCS Tool User Guide
.
Step 5 :
Use the WDDCS Tool's
show
command to view the SEP device handles:
# wddcs show
wddcs v1.1.8.0

Step 6 :
Use the WDDCS Tool's
iom
command to determine which IOM each handle is assigned to:
# wddcs iom
