D280 Upgrade to L 2000

[Paul O'Brien]

Hi,

I have a D280 connected to a HP AutoRaid which holds the OS and Data. The OS is 11.00 64 bit. I want to connect the Autoraid to my L Class and boot from the current installed OS. Has anyone done anything like this or have any suggestions on the likely hood of it working.

hi,

not a thing I would risk for production data. Chances are slim the L2000 will boot because of different hardware paths etc. It might even be a problem to fallback to the D280. I wouldn't try this without a proper backup and an Ignite backup.

regards,
Thierry.

There is very little probability that the L-class will boot and run properly. There are most likely no common I/O cards between the two machines. There is also the possibility that the D280's version of 11.0 64bit (oh, by the way, the L2000 cannot run at all on a 32 bit kernel of any revision) may not have the correct version of kernel routines to support the new L-class CPU and backplanes.

Even an Ignite tape will be tricky to create on the D280. The D280 must have every driver needed (especially LAN and disks) by the L2000 installed, must have all the hardware enablement patches installed, and obsolete drivers (like EISA) removed.

These two boxes are very different architecturally and while a cold install works well (the installer handles the hardware differences), sharing kernels mostly doesn't work.

If your OS and data are on seperate volume groups, then do this:

- backup your data twice
- make two make_recovery backups using the "-i" option and "-A"
- export you data volume group
- switch to L-class
- boot L-class from make_recovery tape
- you will have to MODIFY every single path - and it's not very pretty

As said by others, you are better off reinstalling the OS because it will be cleaner!
