I get the in subject mentioned failure when trying to set the portname to "". When searching for a way to disable the default portname configuration, I did not find something helpful.
With "configure" I can't set this value.
Has someone a hint for me?
From the Command reference manual.. portname ....
The port name is a character string up to 128 characters, including spaces and characters, and excluding commas (,), semicolons ( ; ), backlashes (\), and the at sign (@). To erase a port name, specify this operand as an empty string in double-quotation marks. If the
name includes spaces it must be included in double quotation marks. This operand is optional; if omitted, the current port name is displayed. Some characters require a qualifier or double quotation marks when used with a bash shell; for example, enter a single quotation mark as \', enter an exclamation mark as \!, or enter a pipe (|) as "|".
I enter the following command:
portname 20 -n ""
But when I do this on our Blade SAN Switches with 7.2.0a I get a failure message:
Assigning portname to NULL is not allowed. To set the portname to NULL, please disable the default portname configuration.
So I think I use the right syntax, also because when using the same command on a 5300 with 6.4.2b the command works fine.
So I would like to follow the recommendation, but I don't find a way to disable the default portname configuration as mentioned.
You have to disable the switch first:
Fabric parameters (yes, y, no, n): [no] y
Domain: (1..239) 
Enable a 256 Area Limit
(0 = No,
1 = Zero Based Area Assignment,
2 = Port Based Area Assignment): (0..2) 
WWN Based persistent PID (yes, y, no, n): [no]
F-Port Device Update Mode: (on, off): [off]
Allow XISL Use (yes, y, no, n): [yes]
R_A_TOV: (4000..120000) 
E_D_TOV: (1000..5000) 
WAN_TOV: (0..30000) 
MAX_HOPS: (7..19) 
Data field size: (256..2112) 
Sequence Level Switching: (0..1) 
Disable Device Probing: (0..1) 
Suppress Class F Traffic: (0..1) 
Per-frame Route Priority: (0..1) 
Long Distance Fabric: (0..1) 
BB credit: (1..27) 
Disable FID Check (yes, y, no, n): [no]
Insistent Domain ID Mode (yes, y, no, n): [no]
Disable Default PortName (yes, y, no, n): [no] <<<<<<<<<<<<
Display FDMI Host Name (yes, y, no, n): [no]
Edge Hold Time(Low(80ms), Medium(220ms), High(500ms): (80..500) 
Without disabling the switch it will not show up.
this box runs FOS 7.3.0 BTW.
Thank you for your help.
I will then schedule this for the next maintenance like next year or so ;)
