Need Help With System Recovery After HD Errors

Last week our legacy SCO OpenServer 5.0.6 server started showing "panic" errors about bad blocks/sectors on hard drive. I ran the badtrack command which fully checked the disk, and it identified 2 LBA sectors as bad, and it was unable to recover some of the data. Apparently the lost data had something to do with the scoadmin functioning, because now scoadmin is "not found" when I try to invoke it from the command line.

My plan is to try and migrate the system to a VM and I have found a couple of ways to try - but before I do that I want to try and restore the data that was lost from my last backup tape. I also would like to connect via FTP from another LAN computer, so I can copy files over our network. Right now the FTP connection using the root account fails to let me login.

The main problems I'm having right now are not remembering how to do certain tasks from the command line. I ran an integrity check and created a report, but I can't remember how to print from the command line. I need to find out what printers are available and I don't know how to do that.

So here are my initial specific questions:

what command to I use to show me what printers are available to print to?
what do I need to do in order to allow my root account to login using FTP?

Any help will be appreciated. Thanks!

DESCRIPTION

       HP-UX  supports	MCA Error Recovery to ensure that certain Machine Check Aborts (MCA) caused by transient errors do not crash the operating
       system.

       The dynamic tunable is used to enable or disable the MCA Error Recovery functionality.  If disabled, an MCA will cause the system to initi-
       ate  a  crash dump and then a system reset (normal legacy behavior).  If enabled, certain MCAs caused by transient events will be recovered
       and system execution resumed.  The recovery action depends on the type of MCA and can include termination of a user process.

   Who Is Expected to Change This Tunable?
       System administrators can change the value of depending on the usage of the system.

   Restrictions on Changing
       MCA Error Recovery is only supported on Dual-Core Processors 9100 Series and later.  On unsupported systems, MCA  Error	Recovery  will	be
       disabled by default and changing the tunable will not be allowed.

WARNINGS

       All  HP-UX kernel tunable parameters are release specific.  This parameter may be removed or have its meaning changed in future releases of
       HP-UX.

       Installation of optional kernel software, from HP or other vendors, may cause changes to tunable  parameter  values.   After  installation,
       some  tunable  parameters may no longer be at the default or recommended values.  For information about the effects of installation on tun-
       able values, consult the documentation for the kernel software being installed.	For information about optional kernel  software  that  was
       factory installed on your system, see at
