Ultra 5 Arch (URGENT)

I was trying to migrate a DB into an Ultra 5 and it was easy for me to buy a new 80GB ide disk but OS (Solaris 2.6) does not recognize the disk. OS belives that it is a 8GB disk, my point of view is to try to update the OBP to a newer version. (3.25.3 is the current one )

Does anyone knows if it is possible? or What can I do??

U5 hardware specs

Doubtful that upgrading the OBP will help - if the system sees the drive you can try the procedure below - you are not that far behind on the OBP (latest for Ultra 5 is 3.31.

According to the hardware specs it would not be supported but I found another link about the system not seeing a disk at the correct size - hopefully this will help. If you can see the disk in format, then you can change the size - your next problem may be knowing all the information but I didn't find a problem/solution for an 80GB drive.

Seagate disk ST340824A is detected as a 5.77GB disk, it should be approximately

# format
0. c0t0d0 <ST340824A cyl 19156 alt 2 hd 15 sec 255>
1. c0t2d0 <ST340824A cyl 12007 alt 2 hd 16 sec 63>

The above is an example of a disk (c0t0d0) showing the correct size and a disk
(c0t2d0) showing an incorrect size.

Using the Solaris (TM) Operating Environment format utility, select the problem disk -> type -> other. Then change the disk geometry to the following:

Cyl -> 19156 Alt -> 2 Hd -> 16 Sec -> 255

The steps to change the disk geometry follow:

Specify disk (enter its number): 1

a search on sunsolve returned this.

8. PROM: CP2040 OBP and SMC Flash PROM Update
Patch Descriptions: 112500-01

i dont know if you have access to but it is your best friend. Smilie

it seems to go thru a howto for updateing all of the above.


also trying "Ultra 5 OBP update" as my search criteria on sunsolve returned a decent number of documents reguarding a few things.

from the OBP, you should be able to type 'probe-ide-all' or something to that effect. If the disk shows up fine, then you know the OBP is not your problem. If 'probe-ide-all' does not work, try 'sifting probe' from the OBP prompt. Choose the option that looks best to you.

Hope this helps.
