The replies I got now are very useful as well.
It is possible to install 4.1.3 on a 9GB/4GB disk (though Sun does not
recommend/sell a 9GB internal disk for Sparc20), with partitions not
exceeding 2GB. Or install Online DiskSuite v1.0 to avoid this 2GB
According to Raymond Wong [email@example.com] resolving timeout problems
in format command can be done as follows;
change the value from 120*60 to be 240*60
build a new kernel, install and reboot.
1) attach the new disk[ and reboot].
2) type the following at the command line
adb -k -w /vmunix /dev/mem
sd_fmt_time /W 0t9600
adb will start debugging the active kernel, the second and third
commands to adb. These are temporary changes, and will be gone when
next reboot. That way no permanent changes are made.
3) Format the disk as you were trying to do.
4) As noted in 2), the changes to the kernel will be gone on next
Recommendation from Al Hopper [firstname.lastname@example.org]:
Don't mount disks internally in a Sparc-20. There is just
not enough cooling capacity *and* you are hurting the reliability of
other electronics by introducing more heat from the disk drive(s).
Also don't forget that a Power Supply (PSU) is not 100% efficient.
assume that your Sparc-20 PSU is 80% efficient: So if you ask the
supply another 10 Watts (to a disk drive), it must dissipate another
Watts of heat. This puts even more heat inside the box!
Get an external enclosure with good cooling and mount your new disks
According to Howard Boggs [email@example.com]:
I have installed 4.1.4 on 4GB drives. The biggest problem you run
into is defining the disk geometry. I think the rpm speed on format
only goes to 6000, some of the newer drives are 7200.
Many recommended Solaris and mentioned that 4.1.3 is not Y2KC. Yes, I am
aware of these facts but the non-commercial 3rd party medical application
s/w will not run on any higher versions. I am stuck with 4.1.3.
Can I install 4.1.3 on 9GB, 4GB disks? Can 4.1.3 handle 9GB and 4GB disks?
I am planning to get preferably 9GB disk internal disk for a Sparc-20
machine and plan to install 4.1.3 (I need this O/S for an application s/w).
I don't plan to export the disk.
Anything I must be aware of (patches, cautions, etc) regarding this issue.
Thanks in advance.
