C-series MDS v2.01b switch firmware requirements
■
For iSCSI with C-Series switches, the Fibre Channel port on the C-series switch that
connects to the SR2122-2 must be set to FL-Port mode if using MDS v2.01b or later
switch firmware.
■
For FCIP with C-Series switches, the SR2122-2 must be configured for
useBport
disabled if using MDS v2.01b or later switch FW. Refer to page 62 of the
HP StorageWorks SR2122-2 IP Storage Router Getting Started Guide
for more
information.
ISL loss can result when the SR2122-2 is configured as FCIP and used to extend
B-series switches upgraded to firmware 3.2.x or 4.4.x
When the SR2122-2 is used to extend a fabric between two B-series switches, the ISL may
segment due to a switch firmware upgrade. The new firmware is now aware of SAN extension
gateways such as the SR2122-2 and can now enable ISL R_RDY mode on a port.
ISL R_RDY mode sends ELP with Flow Control Mode 02 and enables connectivity with
WAN gateway products. If a port is ISL R_RDY mode-enabled, it can only receive ELP with
Flow Control Mode 02; ELP with Flow Control Mode 01 segments the fabric.
This mode cannot detect the PID format of connected ports. If the PID formats for two ISL
R_RDY mode ports are not the same, zoning drops frames.
This feature is persistent across reboots and does not require a license key.
Use the
portCfgShow
command to view whether ISL R_RDY mode is enabled on a port.
The switch ports now connected to the Fibre Channel ports of the SR2122-2 must have ISL
R_RDY mode enabled. This is accomplished with the following switch CLI command:
portcfgislmode
[slotnumber/]portnumber, [mode]
slotnumber
- Specify the slot number for a B-Series director. For all other switches, this
operand is not required. The slot number must be followed by a slash ( / ) and the port
number, so that each port is represented by both slot number (1 through 4 or 7 through 10)
and port number (0 through 15).
The B-series Director has a total of 10 slots. Slot numbers 5 and 6 are control processor
cards; slots 1 through 4 and 7 through 10 are port cards. On each port card, there are 16
ports, counted from the bottom, numbered 0 to 15.
portnumber
- Specify a port number. Valid values for port number vary, depending on
the switch type. This operand is required.
mode
- Specify 1 to enable ISL R_RDY mode. Specify 0 to disable ISL R_RDY mode.
This operand is required.
RA/MA8000, ESA/EMA12000 LUNs are initially passed to the SR2122-2 with the
offset included in the LUN numbering.
When LUNs are first presented to the SR2122-2 from an RA/MA8000, ESA/EMA12000 a
“Show Devices” issued on the SR2122-2 may show the LUNs with the offset number
included.
