Getting Ready to Upgrade

You are nearly ready to begin the upgrade itself.

You have two more tasks to do (or three if this is a Trusted System cluster):

Re-run snoop to make sure that there are no more PROBLEMS or WARNINGS.
Follow the procedure in “Running snoop ”, earlier in this chapter.
Back up your system.
See the next section, “Backing Up Your System ”.

NOTE: If the system you are about to upgrade is a Trusted System cluster server, you must "unsecure" it before you can upgrade it. There will be a message in the snoop log to this effect.

To "unsecure" the system, enter the following command on the server:

/etc/tsconvert -r

See “"Unsecuring" a Trusted System ” for more information.

Backing Up Your System

Before you begin the upgrade, do a full system backup. You should back up your data disks and your system (root) disk, but you'll use a different utility for the root disk.

Data Disks

Back these up using whatever utility you normally use to do routine backups. See “Recovering, Moving or Mounting Files from a 9.x System ” for guidelines on recovering this backup onto a 10.01 system.




	NOTE: Use the `-H` to back up all elements of context-dependent files (CDFs). This will allow you to recover the 9.x "DUX" cluster in the unlikely event of a catastrophic failure during the upgrade.

Root Disk

Use the new utility, COPYUTIL.

COPYUTIL creates a complete image of the disk. It is the best way to create a failsafe backup that you can use in the unlikely event of a catastrophic failure during the upgrade.

COPYUTIL is part of the "Support Media" kit which you should have received along with the "Upgrade Tools" package of which this manual is a part. The "Support Media" kit also comes with a manual, the Support Media User's Guide (HP part number 92453-90010).




	NOTE: If you have directories containing operating system files mounted from a disk other than the root disk (for example the `/usr` directory) use COPYUTIL to back up those disks too.

Do the following:

Find the "Support Media" kit and the manual.
Turn to Appendix A of the Support Media User's Guide.
Put the tape or CDROM containing the offline diagnostics into the drive.
Boot the system from the tape or CDROM.
At the ISL prompt, enter:
ode copyutil
Follow directions in Appendix A of the Support Media User's Manual to make a backup of your root disk.




	CAUTION: If this is a Series 700 system, do not rely on your recovery system (made with `mkrs`); it may not be adequate to recover from a crash during the upgrade. Use COPYUTIL. COPYUTIL is supported for all 9.x systems that can be upgraded to 10.01, but the other tools in the "Support Media" package are supported only on 10.0 and later systems.

If your system crashes during the upgrade, or will not boot, see “Recovery from a Crash or Catastrophic Failure ” and the Support Media User's Manual for recovery instructions.
