You’ve locked yourself out of the IBM Storage Manager, have you? Or perhaps you’ve gotten yourself a used unit, but have no password for it.
Telnet to both controllers IP-addresses (or use serial console via 4pin mini DIN plug in top left corner of both controllers), and type
VxWorks login: shellUsr Password: wy3oo&w4 (not shown as you enter it) -> loadDebug value = 1 = 0x1 -> setSAPassword_MT "" ReturnCode = 0x1 value = 1 = 0x1 -> unld "Debug" value = 0 = 0x0 -> exit
This removes the password, so you can configure through the DS Storage Manager without entering a password. Log on to controller B and follow the same steps.
No need to reboot, it should work immediately.
