- Today we received our first R3000 to R4000 Indigo upgrade.
- The SGI engineers have really done a marvelous job of
- engineering -- the whole process, including swapping the
- power supplies was EXTREMELY easy and took less than 10 min.
-
- The only glitch was came when the system wouldn't boot with the
- following error:
-
- _______________________________________________________________
-
- Cannot load scsi(0)disk(0)partition(8)/sash
- Unable to load bootfile; not enough space
-
- Unable to boot; press any key to continue:
-
- _______________________________________________________________
-
- The error message above suggests that partition(8)
- might have been trashed. However, under the miniroot
- I was able to "cshroot" in the disk from Admin.
- Fx showed no problems, and everything seemed in order.
-
- When I explained these symptoms to the SGI Hotline
- representative, his only suggestion was that the
- partition 8 "had been hosed" and suggested that I
- use "fx" to rewrite the partition info, do a mkfs from
- Admin -- i.e. wipe the disk and start over.
-
- This worked except when I did a Restore, the problem
- returned.
-
- Now 8 hours later, I think I see what went wrong.
- The R3K machine was running IRIX 4.0.5F prior to the
- installation. When I installed the operating system,
- I didn't set the "neweroverride" to "on" so the old
- /unix kernel didn't get updated. My hypothesis is that
- when an R4K Indigo attempts to load an R3K /sash
- it fails with the above error message. Is this correct?
- During a "Restore" simply put back the old R3K kernel.
-
- TAKE HOME LESSION?
- If you are currently running IRIX 4.0.5F on an R3K Indigo
- and you get an R4K upgrade kit, make sure you set the
- "neweroverride" to "on" and step through list of
- files and force INST to install eoe1 basic IRIX files.
-
- If I'm wrong in this, please correct me -- I'm just trying
- to save some else the problems I had. Clearly the SGI
- Hotline dude hadn't seen this problem before (or he
- wouldn't have had me wipe my disk clean :-(
