How to remove old HP switch in stacked mode ?

Hi,

 

I've just replaced my HP Procurve 24-port switch with a new replacement unit which was previously configured in a stacking mode of 24-port and 48-port, see below command result:

 

Running configuration:

; hpStack_WB Configuration Editor; Created on release #WB.15.11.0007
; Ver #03:12.15.0d:09

stacking
member 1 type "J9729A" mac-address c4346b-8f0e40
member 2 type "J9726A" mac-address c4346b-970ec0
member 3 type "J9726A" mac-address c4346b-8838c0
exit

......

 

and this is the show stack command result:

 

Stack ID : 0100c434-6b8f0e40

MAC Address : c4346b-8f0e4b
Stack Topology : Chain
Stack Status : Fragment Inactive
Uptime : 0d 0h 14m
Software Version : WB.15.11.0007

2 c4346b-970ec0 HP J9726A 2920-24G Switch 128 Missing
3 c4346b-8838c0 HP J9726A 2920-24G Switch 128 Standby

 

My question is, how can I remove the missing or replaced switch that is in red font ?

 

ANy help would be greatly appreciated.

 

Thanks,

There are also some amber light blinking on the front panel of the switch, see below that I circled:

What command should I type so that those light can turn to green ?

Re: How to remove old HP switch in stacked mode ?

You can remove a member of a stack with the "stacking member N remove" command. You do need to be in the configure context.

If you have a switch that should not be part of a stack anymore, use the "stacking disable" command from the configure prompt. This command will require that the switch reboot. Or if you want to join it to a new stack, use the "stacking factory-reset" command from the configure prompt. Again this will reboot the switch. Both of these commands will turn off the stacking led. It is on because the switch still thinks it should be part of a stack.

For more info, check out the stacking whitepaper: http://h20195.www2.hp.com/V2/GetDocument.aspx?docname=4AA5-7121ENW&cc=us&lc=en

Re: How to remove old HP switch in stacked mode ?

Eric, thank you foryour response. But somehow the command that I tried doesn't seems to be working for the switch:

The switch member ID 2 is still there and I'd like to know how to make the member ID 3 to be active ?

You need to be at the config prompt: 

 

AV_Switch1# config

AV_Switch1(config)#

Hm... i tried that already, but somehow it is giving me:

 

Invalid input: config

 

as the result.

Re: How to remove old HP switch in stacked mode ?

Thats wierd. I would have understood if the prompt looked like this "AV_Switch_1>". That would have indicated that you were at the operator prompt.

 

Do a "?" at the prompt to list the available commands. It should look like this:

 

AV_Switch_1# ?
backup         Backup next startup-configuration file to TFTP server
boot           Reboot the device.
clear          Clear information.
clock          Configure or show the current time, date, and local time offset.
command-alias  Specify a command alias
configure      Enter the Configuration context.
copy           Copy datafiles to or from the switch.
debug          Enable/disable debug logging.
delete         Delete a file

<truncated>

verify         Verify the signature of a switch firmware image.


AV_Switch_1#

 

If that isn't the case and it looks more like this:

 

AV_Switch_1> ?
chassislocate    Control the chassis locate LED.
dir              Display a list of the files and subdirectories

                 in a directory on a USB device.
display          Display current system information.
enable           Enter the Manager command context.
exit             Return to the previous context or terminate current 

                 console/telnet session if you are in the Operator 

                 context level.
link-test        Test the connection to a MAC address on the LAN.
logout           Terminate this console or telnet session.
menu             Enter the menu-based console user interface.
page             Toggle paging mode.
ping             Send IPv4 ping request(s) to a device on the network.
ping6            Send IPv6 ping request(s) to a device on the network.
quit             Exit the current command view
show             Display switch operation information.
traceroute       Trace the IPv4 route to a device on the network.
traceroute6      Trace the IPv6 route to a device on the network.
verify           Verify the signature of a switch firmware image.


AV_Switch_1>

 

Then you have to use the "enable" command first to get to the manager prompt.

Here's what I can see from the ? command and the enable.

I'm connecting to the Commander switch,

Re: How to remove old HP switch in stacked mode ?

Ok, now I get it. The switch is administratively shutdown because it thinks that the rest of the stack is still up and running and has shut down all of its ports to keep from looping the network. I don't have a switch in this state in front of me but we should be able to figure it out.

 

Type the "stacking" command and hit <tab> or the question mark key. There should be a couple of options. I think that two of them are "disable" and "factory-reset".

 

If you don't intend to join this switch to another stack, you can use the "stacking disable" command.

 

If you would like to join this to another stack, then use the "stacking factory-reset" command.

 

Sorry it took a while to get there.

No worries Eric,

 

In the Putty console,:

 

AV_Switch_1# stacking
 factory-reset         Erase the startup config and all knowledge of other
                       stack members.
 set-stack             Makes the inactive stack active.
AV_Switch_1#

 

 

My intention is to remove the member 2 (old switch) and put back the replacement switch from HP into the stacking mode with the 48 ports as the commander :

 

AV_Switch_1# show stack

Stack ID         : 0100c434-6b8f0e40

MAC Address      : c4346b-8f0e4b
Stack Topology   : Chain
Stack Status     : Fragment Inactive
Uptime           : 0d 0h 14m
Software Version : WB.15.11.0007

 3   c4346b-8838c0 HP J9726A 2920-24G Switch              128 Standby

 

so the command is set-stack ?

do I have to remove the missing switch first or set-stack first ?

Re: How to remove old HP switch in stacked mode ?

yes, use the "stacking set-stack" to re-activate the stack. The switches will start functioning again. Then you can use the "stacking member 2 remove" from the config prompt to remove the old switch from the config.

 

The only issue will be that from here on out you will have two members of the stack, labeled 1 & 3.  If you want them to be consecutive, 1 & 2, do this from the config prompt once the stack is active again and the missing / old switch is removed:

 

stacking member 3 shutdown

stacking member 2 J9726A mac-address c4346b-8838c0

 

You may have to power cycle the 24 port switch.

 

When it comes back up, you should have a stack of two switches with the 48 port switch being member 1 and the 24 port switch being member 2.

Many thakns for the assistance Eric,

 

AV_Switch_1(config)# show stacking

Stack ID         : 0200c434-6b8f0e40

MAC Address      : c4346b-8838e3
Stack Topology   : Chain
Stack Status     : Active
Uptime           : 0d 0h 6m
Software Version : WB.15.11.0007

 3   c4346b-8838c0 HP J9726A 2920-24G Switch              128 Commander
AV_Switch_1(config)#

 

now the commander role is hold by the 24 port switch which I haven't swap the member ID.

 

so If I issue the command below:

 

stacking member 3 shutdown

stacking member 2 J9726A mac-address c4346b-8838c0

 

would that be working because it is shutting down the switch first then rename the member ID number ?

Re: How to remove old HP switch in stacked mode ?

and the PS light is still blinking in amber ? is that normal ?

EricAtHP

Re: How to remove old HP switch in stacked mode ?

No, that's not normal. The PS light indicates that there is a problem with the power supply. But the 2920 only has one power supply. Are you using an external power supply? If so, make sure that both the external and internal power supplies are connected and plugged into a functional outlet.

 

I assume you are just using the internal power supply. If that is the case, try removing it and re installing it making sure it gets fully inserted. Remove the power cord first. This will power cycle the switch. 

 

Otherwise, you may have to contact support to get a replacement.

Re: How to remove old HP switch in stacked mode ?

yes, there is only one PSU and I'm using the same PSU unit, the switch itself has been replaced.

 

I guess this time I must log the request to replace the PSU.

Your doubts were already answered here.
