Use scadm utility to reset the admin password:
# cd /usr/bin/cd /usr/platform/`uname -i`/sbin
# ./scadm userpassword admin

Return to the ALOM login prompt
Now, login into the “admin” account using the new password


If the SCADM not available, download the RSC software from MOS:

#/usr/platform/`uname -i`/rsc/rscadm userpassword admin
[To reconfigure the card run the command:
# usr/platform/`uname -i`/rsc/rsc-config

[If you had installed the software before and believe the card is configured check the setup:
# usr/platform/`uname -i`/rsc/rscadm show
