Donald,
You can user another Linux server in you environment to reset the
password.
First, "link/attach" where the minidisk of the "/etc" is on,
and then mount the /etc
The following exsample is for Intel Linux server you will need to
change the /dev/hda1 to /dev/dasd?? value
mkdir /mnt/etc
mount -t ext3 /dev/hda1 /mnt/etc
chroot /mnt/etc /bin/bash
passwd root
exit
unmont

I've inherited a nice little problem....
a Red Hat RHEL 5.4 zLinux system fails on boot requiring me to run fsck
manually , and it then prompts for the root password.
The problem? Nobody knows what the root password is. :-(
I believe we have the system configured so if it comes up in single user
mode, no password is required. (of course we already logged on to the vm
3270/3215 console with a password...)
But... how do I get redhat zLinux to come up in single user mode? Is there
a
loadparm I can specify on the #CP IPL xxx command?
I've also tried #CP VI VMSG 0 1 and get this response:
00: HCPPCX6531E The operating system will not accept commands from the
service
processor.
Thank you
