There is no scadm command for the sun4v architecture on Solaris 10.
Therefore, to reset a forgotten ALOM password, you’ll need to connect the Serial management cable. (For example, I used an Annex terminal concentrator, and then telnet‘ed into the appropriate port on the Annex). Warning: you’ll be erasing your ALOM NVRAM during this procedure, but you have no choice.
Pull both power cables from the back of your (init 5‘d) T2000. Leave them unplugged for 5 seconds, and plug them back in.
Watch as the ALOM initialisation flows past your serial, and when you see the following, hit ESC:
|
1 2 |
Boot Sector FLASH CRC Test Boot Sector FLASH CRC Test, PASSED. |
You’ll know if you’re successful, as you’ll see the ALOM <ESC> Menu:
|
1 2 3 4 5 6 7 |
ALOM <ESC> Menu e - Erase ALOM NVRAM. m - Run POST Menu. R - Reset ALOM. r - Return to bootmon. Your selection: |
First, hit “e” to erase the ALOM NVRAM:
|
1 2 3 4 5 6 7 8 |
ALOM <ESC> Menu e - Erase ALOM NVRAM. m - Run POST Menu. R - Reset ALOM. r - Return to bootmon. Your selection: e ALOM NVRAM erased. |
Then, hit “r” to return to the ALOM boot process:
|
1 2 3 4 5 6 7 |
ALOM <ESC> Menu e - Erase ALOM NVRAM. m - Run POST Menu. R - Reset ALOM. r - Return to bootmon. Your selection: r |
Once the ALOM comes up, you’ll be logged in as admin with no password:
|
1 |
sc> |
Reset the admin password:
|
1 |
sc> userpassword admin |
You’ll need to setup the SC again:
|
1 |
sc> setupsc |
I always add another personal admin user, to save this sort of thing happening:
|
1 2 3 4 |
sc> useradd toki sc> userpassword toki sc> userperm toki cuar sc> usershow |
Check you can access the console, and you’re good:
|
1 2 3 4 |
sc> logout ..login.. sc> poweron sc> console -f |
