Here is the promised (LONG!!!) summary of findings about the problems related to the Seagate Elite 9 - the 9GB disk, and issues that may arise when partitioning it as one large slice/partition.
Last week I asked a question:

Is there > anything in particular I should be aware of??

First of all I would like to thank all the correspondents. It was very helpfull. There were quite a few answers. Some of them right, some quite wrong. There were several "me too-s". I also talked to our local Sun and Digital support, and got some (again: right, wrong ??) answers. There seems to be some confusion in the area - especially regading exporting large partitions...
First of all, under Solaris 2.3 there are NO problems with creating (UFS) file systems larger than 2GB (RTFM: Solaris 2.3 Administering File Systems, pp 55) - Sol23 limit on file system size is 1 Tbyte, and on file size 2GB (maybe the latter is confusing)...
One thing that you may want to note is that (apparently) *both* SunOS 4 *and* SunSO 5 have problems with *formating* large drives due to timeouts. For Solaris 2.3 there is a patch (101788-01) which will (apparently) fix the problem (I deliberately say apparently, since I haven't tried to format the disk - yet ;-). Also, (for SunOS 4 people) you will find the format.dat entry appended below. One person mentioned that there are problems with certain commands which work *only* with raw (/dev/rdsk) devices (i.e. fsck and ufsdump).
The next issue that arose is exporting such a large file system thru NFS, PCNFS and (in our case) CAP (Columbia AppleTalk Package) to Unix boxes, PCs and Macintoshes.
Replies from net were mostly along the line - YES, it is doable, the only thing that will not work are df and du, which will give incorrect results (if you are not running Online Disksuite on SunOS 4). Various people are exporting (read-write and read-only) to Solaris 2.x, SunOS 4 (4.1.3), HPUX (9.0), AIX, IRIX. I belive (and that was also backed up by a number of correspondents) that there is nothing inherent in the NFS protocol that limits the size of the filesystem exported, but your mileage may vary...
Sun support said that there should not be any problems with exporting large filesystem either to other Unix boxes or to PCs (via PCNFS) - df and du will break, but... Digital support (I have 3 Ultrix and 2 OSF 1 v2 boxes) said firstly: YES, it can be done, and then next day (another guy): NO, it will not work. The next version of OSF (3.0) will support filesystems larger than 2GB. So much for the 64-bit operating system... I am still not sure if guys did not confuse NFS and UFS, but... I am going to try and and mount Seagate from both (DEC) platforms.
Finally, as we are also using CAP for sharing home directories to Macintoshes - the people from Down Under said that CAP v6.0 pl 192. will definitely work with large file systems, since patch 191 introduced a routine which will scale down the size of the file system to 2GB (maximum that MacOS can handle).
Last, but not least, I'd like (once again) to thanks all the correspondents. Here is the list (sorted in alphabetical order):

I've asked my supplier about these disks. He claims that they're not quite ready for prime time -- failure rate has been around 20%. His company is receiving 10% of Seagate's allocation (current production is only 200 units/month). Apparently Seagate is backordered on these disks to the tune of 30000 units. Judging by Seagate's production volume I'd say that Seagate is currently producing evaluation unit quantities and that these things shouldn't have been released for general consumption for a couple more months.
Anyway, I'd perform backups frequently and be prepared to lose the disk at any time.

Just *don't format it*, as formatting takes a looong time, and format will time out, possibly corrupting the disk. So just label, partition and newfs. You shouldn't need to format new SCSI disks anyway.

SunOS 4.1.3 sees the NFS mounted drive as a 2 Gb partition (no surprise), but can still see all of the files loaded on the disk (currently about 3.8 Gb). Not sure what might happen with PC-NFS.
We are not NFS mounting the drives for now until we can get a definitive answer on what problems/gotchas might be lurking. Might be safe to mount it read-only, but you never know...

Hi Nino,
I've just purchased two of these drives for my Suns. One machine (mine) is running SunOS 4.1.3; the less critical machine (my boss's) is being upgraded to Solaris 2.3.
I have the 1.3GB "lunchbox" disk drive, so I simply removed the old 5.25" 1.3G drive (having backed everything up, of course), and dropped in the 9GB drive - same mounting hardware and all. The only problem I encountered with the new drive is with the lunchbox's SCSI ID select switch. The pin pitch on the IDC connector does not match the that of the connector block on the new drive, so I simply disconnected the ID switch and hardwired the SCSI ID using the jumpers supplied with the drive.
This is the first time I've been exposed to Solaris 2, and so I was cautious with the installation. But it worked well, and the system came up smoothly. Next step was the formatting of the new drive. Run format as usual, and it automatically detects the drive parameters. In my case, I partitioned the drive as a single partition (s2)...the only confusion I had was answering a question about a "hog partition". I chose the default answer offered (6) and continued. Format asks for a partition name, eg "Elite 9 - Data" and adds an appropriate entry into format.dat, for later recall if required.
A quick(*) newfs to /dev/rdsk/c0t2d0s2 (in my case) and an entry for the mount point in /etc/vfstab, reboot and we're away! I even had the time to let format run a "destructive" surface analysis of the drive before I partitioned the drive - nice to know the disk is safe to use before you get in too deeply.
Hope this helps. If you need any further information, please let me know...
Gary

Well as part of the testing we did create a single 8.43 Gb partition and we were able to newfs it. It would pass fsck using /dev/rdsk/c0t0... but would fail fsck with a seek error using /dev/dsk/c0t0...
However we did not have the nerve to try using it in production. Dump and restore might have been interesting. Two 5 Gb exabytes ?

The next 5 1/4-inch product is a 9 GB disk which requires 3.5 hours to format. We have a compatibility problem here.
We can simply raise the timeout to 4 hours which would easi.ly fix the problem.
One problem with this solution is that you have to wait 1/2-day for the timeout to occur, even for smaller disks which takes less than an hour to format. This doesn't seem terribly flexible.

We have a number of them running on Solaris machines. Nice disks!
Yes, you can keep it as one big partition -- works great. Just a few things to be aware of:
1) Certain commands only work with the raw (/dev/rdsk) device name. These include fsck and ufsdump -- things that would normally work on either the raw or block devices.
2) "du" gets confused.
3) Be sure you know how you're going to back the whole thing up.

Exporting large partitions to other unix machines works fine -- I've done it with SunOS and HPUX machines. "df" no longer knows what it is talking about on those machines, but everything else works fine. I've not tried PC's at all. You could definitely have a surprise there -- try it before counting on anything.
We have a couple of DAT stackers that we got from Artecon. One of them has been backing up a few dozen machines on our net for over a year without trouble; the second was brought in to deal with all these new, large drives. I'm still working out just how I am going to deal with this, though. A lot of our large drives hold observational data and don't need to be backed up, but we will have other stuff as well. I'm thinking about modifying GNU tar to be able to automatically switch tapes when it hits EOT, so a large partition can be backed up without human intervention.

the problem with Sunos that the max number of blocks in a single partition is approx 4,190,000 ( 2**22 ?) due to the number of bits allocated.
NFS doesn't have any such restriction ( at least on the Unix systems here ! )
The problem with df ( and du also I think ) is that they also weren't designed
for such large filesytems and the math in them overflows with these big disks.
DisksuiteOnline makes big filesystems on SunOs by joining disks together etc. so the df in that package was fixed to work with bigger numbers. BTW we don't use DSOL but we stole the df from it to keep our users happy :-)
Don't have Pcnfs here, so I cannot sya if it works in this situation.

I haven't actually go my hands on one of these yet but we have many of the 3Gb Elites working here on Solaris 2 There's no problem with filesystems > 2Gb as there is with SunOs4.1.3.
We select partition 1 or 6 as the whole disk and leave partition ( slice ) 2 tagged as "backup".
The other good thingg is that you can export these large filesystems to SunOs4.1.3 machines and they still work! Although df overflows on the client ( get the one out of Disk Suite Online to fix this).
I have heard that if you want to actually format one of the 9Gbs there may be a timeout problem.

The only way you can make it one big partition is to use Online Disksuite and concatenate smaller partitions together into one big one. Solaris 2.x is still limited to 2Gb (2^31 - 1 bytes) sized filesystems. This won't change until there is a 64bit integer used for seeking within the file. Disksuite provides llseek, a long seek.
In terms of reliability and for backing up I'd suggest making it into 5 smaller partitions (~1.8Gb each).

Sorry, 2^^31-1 maximum partition size on all flavors of SunOS, including 5.3, about 2.14 GB.
Beware, you may find that newfs *seems* to work with a bigger partitions. Be assured you will get an unpleasant surprise down the road if you try it.
If really big single filesystems are a requirement you can either buy Online Disk Suite or switch to AIX or OSF-1. :-)

Nino,
You can actually address a 1 TByte (1000GBtye) disk under Solaris 2.3 (All we need now is someone to start building them). The only caution is that any machines running SunOS 4.1.x or lower can only see 2.0 GBytes, even as nfs clients. If you have any SunOS nfs clients you should be aware of this.

Nino,
It seems that once your NFS server exceeds 2.0 Gbytes, clients such as SunOS machines, Macs running Mac TCP and possible PC's running pcnfs will only be able to address 2.0 GBytes.
I talked to Sun about this and they were unsure as to "which" 2 Gig the nfs clients actually "see". I imagine that the possibility of data corruption under this regime would be fairly high. In my case I had to choose to make 2 Gig partitions for any partitions that SunOS Suns or Macs needed to read or write.
Incidently our SGI machines running IRIX 5.2 were quite happy with up to about 6 Gig. Maybe the 2 Gig limit is a bsd thing ??
Best of luck,

We have two Elite 9's sitting on a SS1000 running Solaris 2.3, each of which contains just one big partition. As long as I keep my SCSI chain relatively short and use Forced Perfect Termination, I don't have any problems.
A colleague of mine has a similar setup and had a few problems with SCSI errors, but he was able to alleviate these by removing some internal jumper to change the termination (sorry I don't have more details on this.)
Good luck with your disk.

I don't think so. The partition limit under Solaris 2.x is still 2.0 Gb, which means that you will need on-line disk suite or something similar in order to 'create' a usable partition greater that 2.0 Gb.

We export read/write. The clients include SunOS 4.1.3 variants and HPUX 9.0 machines. When first testing this out, I would export a large, blank partition to a SunOS machine and use the client to create several GB of files, just to prove to myself that it would work as expected. So far no problems.

As for NFS, I haven't yet attempted to get NFS sorted out. I have a NEC Versa laptop which I use to run NFS. This newer machine replaced an old Versa, running NFS successfully to a 4.1.3 machine. Moving NFS across to the new Versa has not been too successful, yet. I cannot get NFS or Novell up - I'm sure there's a glitch with PCMCIA support or some other $%#%%^ PC funny.... :-{

I say this because we often get usless info from the Sun support people.

Hello. The Macintosh file system can only cope with volumes 2Gb or smaller. CAP patch 191 or later scales larger UNIX filesystems down to fit within this limit. You shouldn't have any problems although the numbers for used and free space may look a little strange.

The scaleVolSize() option is enabled by default. No special action is required in the configuration.

We have 10 of these on one SS10 running 5.3 They work great. We are using entire drive as one partition. You probably want to change the space reserved for overflow (I forget what Sun calls it) to something smaller than the default 10%.

Nino-
We are shareing the filesystems. Under 5.3 they call it share instead of export. Functionally it's the same.
Filesystems are read-write.
'Exported' to SGI Indigo2XL x 3 over FDDI.
I believe that Sun 5.3 is sysVr4 The SGI are running the current IRIX which I believe is sysVr3
We went with the 10% default because the average file size is slightly more than 50meg and there is no on site admin. Admin is done by dialup every couple of days and we felt better having a big cushion.
This equipment is used 24hours/day 363days/year.
