Manageability Optics • HP recommends using DCFM for managing the following environments: pure FOS based fabrics, mixed FOS and M-EOS fabrics where the FOS switch/director is the seed switch. EFCM is the recommended management software for M-EOS only fabrics when a FOS switch or director can not be used as the seed switch. • In a mixed fabric environment, an M-EOS switch must be the principal switch if the fabric is in Interopmode 2 (McDATA Fabric Mode). • FOS 6.2.0e and later support Port Fencing configuration for switches through the CLI. Assistance from service support should be enlisted to enable this feature. With DCFM 10.1.x and later, Port Fencing can be done through the DCFM menu. It is suggested that default parameters for Port Fencing be used to avoid taking ports down for normal fabric events. • Firmware download is executed sequentially if DCFM is used for downloading code to FOS switches. • Fabric administrators should check the Link Incident Report (LIR - Port x "FF") for any failed component incidents in switches/directors as these are not reported to z/OS through the CUP. • As a best practice for deploying FOS switches/directors into a FICON environment, verify the FOS version shipped with the most current FOS recommendation. It is recommended to update all FOS switch/directors to the same FOS levels for production. • Node descriptor information is obtained through the Element Manager instead of the fabric wide node descriptor list when using DCFM to manage M-EOS switches. • When DCFM 10.1.3 is used for managing TI zones, zone propagations may experience a timeout. This issue will be resolved in later FOS releases It is recommended that you use 50 micron multimode fiber optic cabling rated at 2000 MHz-km (OM3 fiber) for connecting to 8-Gb/sec short wavelength (SX) small form factor pluggable optics (SFPs). Other 50 micron and 62.5 micron multimode fiber may be used as an alternative, but distance limitations may exist. 30

HP recommends using DCFM for managing the
following environments: pure FOS based fabrics,
mixed FOS and M-EOS fabrics where the FOS
switch/director is the seed switch. EFCM is the
recommended management software for M-EOS
only fabrics when a FOS switch or director can
not be used as the seed switch.
•
In a mixed fabric environment, an M-EOS switch
must be the principal switch if the fabric is in
In-
teropmode 2
(McDATA Fabric Mode).
•
FOS 6.2.0e and later support Port Fencing config-
uration for switches through the CLI. Assistance
from service support should be enlisted to enable
this feature. With DCFM 10.1.x and later, Port
Fencing can be done through the DCFM menu. It
is suggested that default parameters for Port Fen-
cing be used to avoid taking ports down for normal
fabric events.
•
Firmware download is executed sequentially if
DCFM is used for downloading code to FOS
switches.
•
Fabric administrators should check the Link Incident
Report (LIR - Port x "FF") for any failed component
incidents in switches/directors as these are not
reported to z/OS through the CUP.
•
As a best practice for deploying FOS
switches/directors into a FICON environment,
verify the FOS version shipped with the most cur-
rent FOS recommendation. It is recommended to
update all FOS switch/directors to the same FOS
levels for production.
•
Node descriptor information is obtained through
the Element Manager instead of the fabric wide
node descriptor list when using DCFM to manage
M-EOS switches.
•
When DCFM 10.1.3 is used for managing TI
zones, zone propagations may experience a
timeout. This issue will be resolved in later FOS
releases
