HP StorageWorks Fabric Interoperability: Merging Fabrics Based on M-series and B-series Fibre Channel Switches Application Notes (AA-RUQQL-TE, November 2009)

2. Enter the command firmwaredownload –o.
Firmwaredownload –o does not check whether the switches in the fabric support HCL. If the
normal checks are successful, it proceeds and displays the normal message and an additional
message.
The firmwaredownload –o command upgrades both CPs in the switch.
NOTE:
If you want to upgrade one CP only, use the -s option.
You can use the firmwaredownloadstatus command to get the status of this firmware
download. The firmwaredownload –o command causes a warm and nondisruptive boot on
the active CP, but requires that existing Telnet, Secure Telnet, or SecureShell sessions be restarted.
You have elected to bypass the checking of Coordinated HCL. This may cause
traffic disruption for some switches in the fabric.
Do you want to proceed?
If you select yes, firmwaredownload proceeds and failure of the pause protocol is ignored.
Segmentation errors
Use DCFM or EFCM to view segmentation information. Table 20 describes the segmentation event
data codes defined for DCFM and EFCM.
Table 20 Segmentation event data
DescriptionEvent data code
Segment not defined0
Incompatible link parameters1
Duplicate domain IDs2
Incompatible zoning configuration3
Build fabric protocol error4
No principal switch5
No response from the attached switch6
For M-series products, segmentation information can be found in the DCFM or EFCM event logs. To
open the event log from DCFM or EFCM, select Logs > Event Log.
NOTE:
The Description field provides the fabric activity at the time of the event. Byte 4 in the event data field
provides the event code (see Table 20). For example, if byte 4 of the event data field is 01, the
segmentation was caused by an Incompatible Link Parameters error. Byte 0 of the event data provides
the port number. For example, if byte 0 is 04, port 4 is the source of the error.
