You never know: SCO Openserver 5.0.7 P2V

SCO Openserver 5.0.7 P2V

Had to get an old Physical SCO Openserver 5.0.7 Server V'd. The below is a rough step by step guide to remind myself more than anything. I know little about SCO and muddled through this with help from colleagues familiar with SCO and a bit of the old google magic. (Using ESXi 4.0.0 Update 2):

 

^{Perform a manual P2V of a running SCO Openserver 5.0.X}

This is only possible if the Physical SCO Server is NOT using any physical serial cards or other hardware that will not be available in a VM.

Prepare VM

• Create a blank VM on an ESXi Server 
                            with the following settings:

  • Single vCPU

  • Flexible Type Network Adapter

  • IDE Hard Disk

• Boot the VM from a SCO install media .ISO. 
                            Thes can be downloaded from the SCO website:

  • 5.0.7 .ISO

  • Install SCO O/S (you will need a 
                                                       valid licence number and code.

  • Configure Networking. Flexible vnic 
                                                       adapter will show as an AMD PCNet-PCI Adapter Compatible

 

Backup Data

• There are 2 methods to backup the 
                            physical server and restore the data onto the VM:

• 1) Backup locally and copy cpio archives across to the VM

  • +*find / -print | cpio -ovfB | split -b 1024m - /u/backup.cpio*+

  • This will backup everything from /  down to 1Gb files () in /u named backup.cpioaa, backup.cpioab, backup.cpioac ...

  • scp /u/backup.cpio http://www.360doc.com/mailto:[e-mail]:/u*

 

• This copies all generated archives across to the VM SCO server prepared above

• Now restore the files with the  following command on the SCO VM:

  • +cpio -ivdmluI /u/backup.cpioaa,/u/backup.cpioab,/u/backup.cpioac...+*

This method requires sufficient free space on the physical server

• 2) Copy the data straight across to  the SCO VM from the Physical Server

  • Run the following from the VM SCO  Server:

  • +*ssh http://www.360doc.com/mailto:[e-mail] "cd / && find / -print | cpio -ovfB" | cpio -ivdmlu*+

 

Whichever method used will throw some errors about read only files. These will be configured during subsequent operations which relink the kernel - Don' Panic!!

Configure VM

Do not have both physical and VM

servers on the network at the same time from now on - SCO will detect a

duplicate licence

• Configure networking

  • Remove Network Adapter from scoadmin network - This is the config for the physical adapter in the 
                                                       physical server and is no longer valid in the VM

  • Add in the vnic adpter (as above in Prepare VM step) and configure network address etc

  • Relink Kernel etc when prompted

• Configure the Hard Drive

  • Run the following to add config for the virtual IDE hard disk:

  • mkdev hd 0 0

  • This will prompt for setting up a new disk. You want to answer everything so that only the bare config as 
                                                       added, but no work is done initializing this new disk. Answer the prompts as follows:

    • Continue? = y

    • HD 0 Config? = q

    • Partition Table? = q

    • Division Table? = q

    • Bad Track Table? = q

    • Preserve Additional Filesystems/divisions? = y

    • Manual Adjustments? = n

  • This will complete with an error  saying:

    • filesystem construction unsuccessful

    • This is good - it means the HD config was added without altering the contents of the disk

  • Edit /etc/default/boot:

    • Add the following to the DEFBOOTSTR  line:

      • disable=mdac Sdsk=wd(0,0,0,0)

      • so the line reads

        • DEFBOOTSTR=hd(40)unix swap=hd(41) dump=hd(41) root=hd(42) disable=mdac Sdsk=wd(0,0,0,0)

      • mdac refers to the HDD controller used by the physical Server. This can be found by running:

        • hwconfig | grep disk

      • and reading the ht=XXXX  value.

  • Now sync changes to disk and reboot:

    • sync;sync;sync;reboot

• COMPLETE

 

 

This has been tested on 5.0.7 from

an Acer Altos Server with Mylex AcceleRAID ctrlr
