Creating Partitions FDISK

[Fixles]

Hello All,

One of my SCO Open Server 5 servers (A HP ML570 G2) Is randomly rebooting itself. HP have sent me a temporary replacement server and want to whip mine away for diagnostics including the SCSI disks

I have boot and root disks and taken a full backup to tape. I've been told that if I partitions with exactly the same geometry I can just restore....... How do I set up the partitions with FDISK?

This is the output from divvy -P -N

0              0          20479   boot       EAFS
1          20480        6164479   swap       NON FS
2        6164480        8212479   root       HTFS
3        8212480      142245109   data       HTFS
6      142245110      142245119   recover    NON FS
7              0      142249183   hd0a       WHOLE DISK

Any help would be greatly appreciated.

Many Thanks,

James

Hi,

Backup is a script using the cpio command. I didnt write it but i'm assured it backs everything up.

I hopefully have the cpio command to restore from tape. I just need to set the partitions up exactly the same.

With a cpio backup you don't need to have the partitions (fdisk) nor the divisions (divvy) set exactly the same.
If the replacement server is EXACTLY the same as the older then you may just restore provided the filesystems are large enough.
How do I set up the partitions with FDISK?
Use whole disk for unix.

Excellent that will make things a lot easier. What about setting up the swap partition?

Cheers,

James

The swap division is usually set to 1.5 times the RAM size.

Which command do I use to set swap up? I've got 4GB of RAM

 

[PHV]

The swap is defined during the divvy.

Or you can download Microlite Edge from

http://microlite.com

and use it to make boot recovery disks and a backup that will restore your entire system without reinstalling and without you having to know anything. The download runs for 60 days so plenty of time.

I do not trust SCO's boot recovery disks or a cpio backup. See

You SHOULD own this, but Microlite doesn't mind if you use it for this. Lonetar

http://www.cactus.com

is a similar product. You should use one of them.

Welcome back, Tony.

I generally reload the OS and change the filesystems because I always have figured out a better way and resize stuff when it is time to do a recovery. And likely as not to do a tar extract from the edge tape.

 

[Fixles]

divvy did the trick. I've managed to get the partitions set up exactly the same now. Thanks for your help.

Just having a few problems with cpio command.

I'm entering cpio -icvdma -I/dev/rct0 and i'm getting the following error

dynamic linker : cpio : could not open /usr/lib/libsocket.so.2

libsocket.so.1 exists and i tried just creating a link to that called .2 but it didnt work. Any ideas?

Cheers,

James

Ed:

You can resize file systems with Edge or Lonetar. You have the option of putting them back as they were, automatically resizing, or controlling the whole thing manually.

You can also restore on different hardware that requires a btld.

You do not need to reload the OS prior to restore if you use these.

Iknow that is intended. In the meantime I am still in the process of migrating from 4.2 to 5.0.5 and resolving issues, including those with edge 2. whatever and the upgrade 2.01.
Once I have the roughly 10 machines the same and the networking up and running I'll get to the rapid recovery.
