Sun solaris 5.9 to 5.10 upgrade
Hi Gurus,

Need help with upgrading the solaris from 5.9 to 5.10. Any pointers will be great.

Currently we are using 5.9 and need it to be upgraded onto 5.10

Code:
bash-2.05# uname -a
SunOS 5.9 Generic_122300-08 sun4u sparc SUNW,Sun-Fire-V245

this server doesnt have internet access so at the moment i have downloaded solaris 10 update 10 iso image for sparc systems and uploaded onto server.

Let me know if you need any more information

As per normal, you need a recovery route if things go wrong. Take a full backup and ensure you know the restore methodology.

If you burn the cdrom for the O/S and boot from it then the upgrade option should be offerred to you.

Code:
 
boot cdrom

Hi hicks,

Thanks for quick reply. I am supporting this production server remotely.
Got couple of questions
1. If we boot from cdrom do we need to repartition everything or does it only upgrade the os files and rest leaves as it was before?
2. While upgrading if something goes wrong then we may be losing the previous version of os and its configuration

Thanks

Replies to questions:-

1. It should boot from cdrom, take a look around, and see that it's an installed system. It then should give you the option to "upgrade". (If it doesn't just exit and post mortem; no harm done. It should also ask you whether you wish to "preserve" the contents of the other (non-root) filesystems it can see. Say yes to that. No, it shouldn't want to repartition everything in this scenario. Don't select "initial install" option.

2. As a good sysadmin you must know that in IT anything that can go wrong often does go wrong. It is possible (but not likely) that you could be left with a mix-up between versions. If this is a production system then there must be an existing backup strategy; what is it?
What type of filesystem is it? On Solaris 9 I would expect it is ufs?
If so, in the absence of an existing backup method, I would suggest taking a ufsdump of each filesystem to a tape or remote (nfs mounted) disk.

What separate filesystems do you have? Is /usr a separate filesystem?

Hi,

The file system type is ufs as you predicted. for backup there is script that runs on windows which sync the server data on to a particular location. below are the output of mount and df commands.

Small question for booting with cdrom i think we a need a gui interface for that.
Code:
 
bash-2.05# mount

The Sparc usually has a network management port on the back which connects to the System Controller (ILOM/ALOM). If this has been given an IP address (different from the main interfaces) and you can connect to that then you have a "console" connection. No GUI needed; just raw text mode. However, if you're remote and the network management port hasn't been already set up, you've got a problem. (You can't do a O/S upgrade in multi-user mode.)

Notice that you seem to have Oracle on here. Oracle dB should be stopped before a ufsdump is taken (but you probably know that already).

You've got a volume manager running here too. However, in terms of backup I would say you should ufsdump d0,d2,d3,d4,d5 and d6.
