Brocade 4Gb SAN Switch for HP p-Class BladeSystem chassis Early versions of the 4Gb SAN Switch for HP p-Class BladeSystem units have the potential to interfere with a Cisco GbE3 switch being removed or installed into the adjacent slot. Obtaining a PKI Certificate for Secure Fabric OS For information on activating Secure Fabric OS go to the following HP web site: http://www.hp.com/storage/go/secureos Also, you may refer to the Secure Fabric OS Administrator's Guide, Chapter 2, "Preparing the Fabric for Secure Fabric OS," for specific procedures. Non-default operands The use of non-default operands for diagnostic commands is recommended for advanced users and field support only. Need to turn traps on manually The SilkWorm and FA traps in pre-Fabric OS 4.4.0 code were turned on and off as a group; and it wasn't possible to set individual SilkWorm or FA traps. In 4.4.0 the ability to turn traps on and off individually was added. That means, that individual traps need to be turned on explicitly after the corresponding trap group is turned on. After the upgrade from Fabric OS 4.2.0 firmware, individual traps are turned off by default even if the corresponding trap group was turned on before the upgrade. Therefore if you have been previously monitoring these traps, you need to use either snmpMibCapSet or the newer snmpconfig command to turn the desired traps on individually. The default setting is for all traps is Disabled. Save the zone database configuration immediately after an upgrade When considering an upgrade to a later Fabric OS release the user should save the zone database configuration immediately following the upgrade. Changes to the zoning database can then be conducted. If you are considering downgrading to the prior Fabric OS release, remember to clear the zoning database then restore the saved zoning database configuration prior to the downgrade. In a large fabric with a large zoning database (e.g., 2560 ports with a 1MB zoning database), a non-disruptive firmwaredownload on a SAN Switch 2/16V or SAN Switch 2/32 can result in an E_port offline transition. The E_Port offline transition causes a fabric reconfiguration and can cause momentary frame loss. 4Gb switches do not experience this issue. Fabric OS 5.0.5c 9

Non-default operands
The use of non-default operands for diagnostic commands is recommended for advanced
users and field support only.
Need to turn traps on manually
The SilkWorm and FA traps in pre-Fabric OS 4.4.0 code were turned on and off as a
group; and it wasn’t possible to set individual SilkWorm or FA traps. In 4.4.0 the ability
to turn traps on and off individually was added. That means, that individual traps need
to be turned on explicitly after the corresponding trap group is turned on.
After the upgrade from Fabric OS 4.2.0 firmware, individual traps are turned off by
default even if the corresponding trap group was turned on before the upgrade.
Therefore if you have been previously monitoring these traps, you need to use either
snmpMibCapSet
or the newer
snmpconfig
command to turn the desired traps on
individually.
The default setting is for all traps is Disabled.
Save the zone database configuration immediately after an upgrade
When considering an upgrade to a later Fabric OS release the user should save the
zone database configuration immediately following the upgrade. Changes to the zoning
database can then be conducted. If you are considering downgrading to the prior
Fabric OS release, remember to clear the zoning database then restore the saved zoning
database configuration prior to the downgrade.
In a large fabric with a large zoning database (e.g., 2560 ports with a 1MB zoning
database), a non-disruptive
firmwaredownload
on a SAN Switch 2/16V or SAN
Switch 2/32 can result in an E_port offline transition. The E_Port offline transition causes
a fabric reconfiguration and can cause momentary frame loss. 4Gb switches do not
experience this issue.
