HPe ProCurve 2920-24G Switch (J9726A) VLAN issue

Hello all.
I have an issue with my HP 2920-24G Switch (J9726A).  (I have two 2920 in stacking)
I need to increase vlan number.

From the documentation, I found that increase command is:
HP Switch(config)#: max-vlans 999  (This command will take effect after saving the configuration and rebooting the system.)
HP Switch(config)#: write memory
HP Switch(config)#: boot  (Device will he rebooted, do you want to continue [y/n]? )

This is my problem, I can’t restart my switch (stack). Last time when I restarted the switch (stack) the stack restarted both switches in the same time.
To restart both switches simultaneously is a problem for me because have hyper-v cluster which depends on the network (hyper-v heartbeat).
After researching, I found that restart switch in stack should not boot both switches  simultaneously.
I understand that standby switch supposed to be boot first and then the commander switch.
If I`m not mistaken this is a priority configuration. Commander should be priority 255 and standby 128. In this case the boot will work correctly (one by one with no downtime).

I will appreciate any help or suggestions.

How can I correctly restart my stack with no downtime?
Is there an option boot switches one by one manually (not hard boot)?
If it can`t be possible with no downtime, what can you suggest if I need a lot of vlans. I need transfer more than 300 VLANS from port 1/9-2/9 (connected to firewall) to TRK3-TRK4 (trk3/4 connected to my virtualization). In HPe virtual connect I use VLAN tunneling.

Thank you.
Aleksei.

Hello

I thought the correct command was: boot system.  And i thought this would reboot the commander first and after that all  the other members of the stack. But i am not 100% sure.

If you have physical access to your stack, you can just power off the switches 1 by 1 manually?

Hello. 

Thank you for the answer. 

I tried today to manually power off them 1 by 1.

But the parameter max-vlans had not changed. More precisely: the show vlans, shows “Maximum VLANs to support : 999”.
If I try to create new VLAN, I have an error “Maximum number of VLANs (258) has already been reached

Hi Mario_B.

Now I use 258 VLANS, it is more than 256. 

258 VLANS, it number that we set for test in the past.  

Now I set new value max-vlans 999 and the switch still wait for reboot. (After hard boot), it looks like hard boot did not upload the new configuration and now I need to reload or boot the switch. And the problem is that I am not sure if command boot will take down both switches or one by one.

From my switch:

In this document, I see that the switches series 2920 (my switch is J9726A) "supports IEEE 802.1Q (4,094 VLAN IDs) and 1022 VLANs simultaneously"

Re: HPe ProCurve 2920-24G Switch (J9726A) VLAN issue

 

Hi all.
Can someone help me with my issue?

Is there an option boot switches one by one manually?

What is the difference between reload, boot and reboot from the web menu?
Which one of the command makes restart to the stack (two member in the same time) and with command makes restart member by member in the stack?

Thank you,  

Aleksei

As far as i know, boot is for rebooting the whole Stack and with reload you can restart a member from a stack.

See for example here:

Thank you  RenRom1.

I saw that and tried. It not works for my. My switch didn`t  recognize the command reload 1 .
In the post they speak about Aruba S3500, as far as I know in different series they have a different manage options.

I gues if you do a reload (without any paramaters, or may an at if you want it at a later time) @ the member switch that only the member switch will restart and not the entirly stack.
