Zone name restrictions, Enabling and disabling interoperability mode – HP Brocade 4Gb SAN Switch for HP BladeSystem p-Class User Manual

222 Configuring interoperability mode
•
Zone configurations that use either physical port numbers or port IDs are not supported in
interoperability mode. Zoning using port numbers uses the actual physical port numbers on the switch;
for example slot 1, port 5.
•
When a zoning configuration is not in effect, by default all ports are isolated and traffic is not
permitted. This is unlike HP StorageWorks behavior where Interoperability mode is off (and all data
traffic is enabled).
•
HP StorageWorks SAN Switch 2/8-EL, SAN Switch 2/8V, SAN Switch 2/16, SAN Switch 2/16V,
SAN Switch 2/32, SAN Switch 4/32, Core Switch 2/64, and SAN Director 2/128 provide
hardware enforcement of the port WWN zones only for devices attached to their ports. Devices
attached to end-ports on non-HP StorageWorks switches or HP StorageWorks 1 GB switches are
enforced by Name Server (soft) zoning only.
•
Advanced Web Tools can be used for zone configuration as long as HP StorageWorks switches are
connected directly to each other. If Advanced Web Tools is used to set up zoning, then it must be
used as the only zone management method.
•
HP StorageWorks switches connected to a McData switch receive the effective configuration when a
zone merge occurs. (McData only has an effective zone configuration and discards the defined zone
configuration when it sends merge information to the HP StorageWorks switch.) However, a zone
update sends both the defined and the effective configuration to all switches.
•
When an HP StorageWorks switch or director is reconfiguring, wait until the fabric routes are
completely set up before entering zoning commands that must propagate to other switches. Use the
fabricshow
command to verify that all fabric routes are set up and all switch IP addresses and
names are present. (The
fabricshow
command only shows the WWN and domain ID for switches
from other manufacturers.)
•
The maximum number of items that can be stored in the zoning configuration database depends on
the switches in the fabric, whether or not interoperability mode is enabled, and the number of bytes
required for each item.
You can use the
cfgsize
command to check both the maximum available size and the currently
saved size. If you believe you are approaching the maximum, you can save a partially completed
zoning configuration and use the
cfgSize
command to determine the remaining space.
Zone name restrictions
The name field must contain the ASCII characters that actually specify the name, not including any
required fill bytes. Names must follow these rules:
•
Length must be between 1 and 64 characters.
•
All characters must be 7-bit ASCII.
•
The first character must be a letter, which can be either upper case (A-Z) or lower case (a-z).
•
Any character other than the first character must be lower case (a-z), upper case (A-Z), a single-digit
number (0-9), dash (-), or underscore (_).
Enabling and disabling interoperability mode
Before enabling interoperability mode, inspect the individual fabrics for compatibility.
•
Make sure that zones meet the zone criteria and restrictions listed in ”
•
Use the
msplmgmtdeactivate
command to disable any platform management functions. (Refer to
the HP StorageWorks Fabric OS 4.x command reference guide for additional command information).
