C-Mode 8.1.1 Panic Can't find device with WWN 0x611852288

looney_pantz — Thu, 05 Jun 2025 06:18:52 GMT

I've just installed the c-mode simulator into my Vshpere 5 environment I've not done any reconfiguring of the system yet. On initial boot before I've even had a chance to start running the setup I get the following error message.

PANIC: Can't find device with WWN 0x611852288. Remove '/sim/dev/,disks/,reservations' and restart.

Has anyone else encountered this error?

Thanks in-advance.

Yeah, I'm seeing it.. No resolution yet.

Was this after changing the SN and Sys ID at the VLOADER> prompt? That's when I'm seeing it...

after you type boot

you get to the options of ctrl-c

click ctrl-c

boot into option # 4 - that should work

When you start, go to the boot menu and clear configurtation.( Ithink it is option 4)

After that you will be able to start.

Kind regards,

Gerard

I am using 8.1.1 7mode. I still get panic (can't find device WWN) after I change Serial to other number.

I choose option 4 as you mention

thanks

after option 4, what I did is I go to the maintenance mode and assign all disk to the controller, and then go back to option 4 to let it automatically reconfigure, it will be working fine after the reboot.

Those steps work for me to change SN, but HA in 8.1.1-7mode still doesn't work.

Error message "Controller Failover is licensed but takeover of partner is disabled due to reason : Controller Failover not initialized"

Set up the simulator, e.g. at first startup, Ctrl+C into Boot Menu and choose option 4 to initialize, then go through setup to assign hostname, IP, etc.
"priv set advanced"
"useradmin diaguser unlock"
"useradmin diaguser password" and enter a new password
"systemshell" and login with username diag and the password you just created
"sudo rm /sim/dev/,disks/,reservations"
"exit"
"halt"
Reboot VM, Ctrl+C at first prompt so you get into the Loader
"set bootarg.nvram.sysid=1111111101" --> change number as needed
"set SYS_SERIAL_NUM=1111111101" --> change number as needed
"boot"
Ctrl+C to get into Boot Menu
Choose maintenance mode
"disk assign all"
"halt"
--> Simulator will boot up fine with new serial

This also worked for Cluster Mode, just some of the commands changed a bit:

Set up the simulator e.g. at first start up, Ctrl+C into Boot Menu and choose option 4 to initialize, then go through setup to join the cluster.
set advanced
security login unlock diag
"security login password diag" and enter a new password (twice)
systemshell -node <nodename of second node>
sudo rm /sim/dev/,disks/,reservations
system node shutdown -node <nodename of second node>
reboot VM, press <space> at first prompt so you get into the Loader
setenv bootagr.nvram.sysid=4034389062
setenv SYS_SERIAL_NUM=4034389-06-2
boot
Ctrl+C to get to Boot Menu
Respond 'y' to the "Override system id?" prompt.
Choose maintenance mode
disk assign all
halt
--> Simulator will boot up fine with new serial

Thanks Keith - This worked perfectly for me with my cDOT 8.2 sims.
