External SCSI emulation???

Hallo folks,
I have one maybe a little bit silly question.
I would like to gain some experience on field of clustering, but my problem is, that I am not an owner of external storage.
Finally I have for my testing needs available only 1 x old Sun Fire V120 and two old PC's.
My question is, if is possible to make some emulation of external storage on second box and simulate in this way external SCSI storage???
Because my equipment resources are very limited I'll really appreciate any valuable advice, how to build usable test cluster from these old stuff.
My idea is to build something like emulation of SCSI external storage and make this resource availabe like global file system to SunFire box.On SunFire configure two non-global zones and make resources / HA storage, HA services / failover between them.
I am the very beginner so please correct me If my idea is not the right one.
I attach small draft for better explanation....

Thanks folks for any valuable hint....
Greetings from Prague

Hello Tim,
thanks a lot for your hint.
I hope, that I understand you well, so please correct me if I say something wrong.
Your hint is to install Sol 10 / 32bit release / on two old x86 boxes, on these boxes also install Sun Cluster in 32 bit release.
As a second step to install Sol 10 and Sun Cluster also on V120 box and set as iSCSI target previously installed x86 boxes.
Whole connection then will looks in this case like this.....
|         |        ethernet
| x86 |----------------------------|                                          _______
|         |                        __|___________                   |              |
----------                         | ethernet switch |_________|   V120   |
_____                         |_____________| ethernet    |_______|
|         |                           |
| x86 |---------------------------|
|         |      ethernet
----------In this point I have a question, these x86 boxes will in this case acts as cluster nodes or only like a quorum servers / storages /???
Sorry for my drafts, the makes my imagination better.
Thanks Tim

OS 8.1 - Trying to partition an external scsi drive and backup data.

Have an Apple PowerMac 6000 series minitower at work. It runs a program called 4D, that is a database we use to catalog images. Since I've been with the company, there has been no backup of the database, as an external scsi drive had died and never been replaced.
Since the system is running OS 8.1, I wasn't sure how I could do any sort of network backup, and in the end I managed to get a new 50-pin scsi 50GB LaCie External Hard drive with the 25-pin cable to connect to the PowerMac. Connected it yesterday, and it did appear on the desktop as you'd expect.
But when I went to point 4D to the drive, it didn't seem to recognize the file system. I tried erasing the drive, but it had the same probem. Norton Utilities is on the mac, so I tried replacing the partition. Specifically, I tried creating two partitions. One that's 40GB, that I could do 4D backups to. The other, the remaining space (about 7GB) so I could try to copy the entire drive to that partition and maybe even boot from it if the other drive failed.
However, the drive was still mounted when I tried to repartition and it ended up causing an error. I tried rebooting, and the drive wasn't showing on the desktop, but it still wouldn't repartition. Not knowing was else to do, I low level formatted the drive, told it to write zeros to it, and then create the two partitions. Given I was doing all this on a Saturday and didn't know how long it would take, I left it running in the background to check on Monday.
Anyone have any experience with OS 8.1? Is there a program like Carbon Copy Cloner that works with that OS? And any thoughts on what I'd need to do to get this drive working as indicated above? I started using Apple again with OS X, and it's quite a bit different than 9 and previous. Could sure use some help.

Hi, merkman2001 -
I would use the Apple utility Drive Setup (which comes with a normal OS 8.1 install) to initialize and partition the drive, rather than Norton or any other third-party utility.
As far as the format type goes, select Mac OS Extended when asked.
<hr>
Is there a program like Carbon Copy Cloner that works with that OS?
Generally such is not needed with OS 9 and earlier OS versions. All pre-OSX OS's and software can be copied using a Finder (drag and drop) copy process, and remain usable.
This means that the System Folder on the internal drive can be dragged to the icon of the external drive and dropped into it. Ditto any/all additional folders, those containing the programs and documents.
You should be able to successfully do a test boot using the freshly-copied OS on the external drive; this is the best way to verify the integrity of the copied OS.
Can't recall if aliases were used in OS 8.1. If they were, it may be necessary to 'fix' any of them used, since the pathname contained in an alias is not corrected when it is copied to another drive - it continues to point to the original original.
You can also copy the entire source drive to the external one in one action - drag the iccon of the internal drive to that of the external one and drop it in.
After Finder gets done copying everything (this may take some time, so disable any sleep mode or screensaver), there will be a new folder on the external volume - this folder will be named the same as the internal drive. Inside that folder will be a copy of everything that was on the internal drive, including everything left lying around on the desktop and anything left unemptied in the Trash (these will be placed in new folders named "Desktop" and "Trash" respectively).
In order to make that external volume bootable using the freshly copied OS, move the System Folder out of the folder it was copied into, so that it is at the root level of the drive, meaning visible in the window that appears when you first open the drive's icon.

Sparc Station 10 external SCSI Problems

Hi folks,
i have installed Solaris 8 (10/01) on a Sparc Station 10.
All worked fine, except, that only 2 drives from the external SCSI-Array (4 drives ) are recognized by the system.
The format-command hangs for more than 5 Minutes after starting it and then displays ALL drives, but 2 of the
ext. are shown as unknown drivetype.
In the diag probe-scsi-all, all drives are showed correctly.
The SCSI configuration: 3 SCSI Controllers .
2 internal HD's (1.0 GB) and (i hope for the future) 4
external. CDROM is attach one the external connector
from the internal drivecontroller.
Any ideas... ?
Thx in adavance.
Peter
[email protected]

hi,
usually when you see 'drive type unknown' it means that the system does not recognise what type of disk it is. you could try selecting the disk, reformat it or give it a 'type'. failing this, it is a new disk required..
hope this helps

Using external scsi for internal drive.

Hi people. I have a beige g3 desktop and recently bought a sound card (pro tools project pci) that has a scsi port for external drives. The card wont work without a drive atached, and I was wondering if I could use a 50 pin centronics to 50 pin internal cable adapter to use an internal scsi inside the g3.
External scsi cases are cheap but I am trying to make some sort of portable set up and would love to avoid them.
I saw adapters on the web but could not find any here (argentina) and it is a headache to get one sent here.
Anyone have any experience with this?
Thanks in advance
Pepo

I've never used the Digidesign Pro Tools Project card, so is the external hard drive strictly needed to terminate the card's SCSI bus or does the card's configuration software require it? If you just need termination, is the card's external port the HD-50 SCSI-2 type? If so, would this active terminator solve the problem? If the interface isn't the correct one to match the one on the PCI card, could you connect a Centronics-50 active terminator to the end of the cable?
If you need to have a hard drive connected with the setup, were you planning on running the external cable through an unused PCI slot opening in the back? For a clean-looking installation, you could install an adapter like this one, in place of the PCI slot's blank cover. Unfortunately, it prevents the use of the PCI slot for other cards, and this adapter has an external DB-25 port, requiring the adapter to Centronics-50. A standard 50-conductor SCSI ribbon cable would connect between the hard drive and the interior port on the adapter card. I don't know if you've noticed, but just behind the left-side drive bays in the G3 desktop, you'll see a removable piece of metal that closes off the inside corner of the drive bay chassis. You can remove that piece of metal, and provide a path for the drive's data cable to reach the PCI slot area of the computer. It's easier than routing the cable back through the slot behind the CD-ROM drive, which is usually too crowded with cabling anyway.

Mystery with SE3320 - Error message "External SCSI BUS Reset

We have had this problem for several weeks and have been unable to resolve with much trial & error attempts.
Appreciate the help of the Sun community!
=============
*Initial Problem: During Sybase installation on E2900 server. During "create database" stage, which involved a lot of harddisk operation, the system showed external reset error message for several disks on StorEdge 3320
During mirroring process, we always getting error message "External SCSI BUS Reset" then "target xxxxxx reduce sync transfer rate". We suspect that we have a wrong cable as of we are using P/N 530-3631-01 instead of 530-3631-02 as mentioned on SE3320 Product Manual. Unfortunately, we do not have the suggested cable with us, if you believe the problem is with the cable? Now we are trying to re-seat connections as well as change available SCSI cables just to find our luck. We are also suspicious if we need jumpers and terminators.
2 (two) faulty storages condition now is still in the SAME with condition when we raised complaint which is error message during high load I/O operations. In total, we have 6 SE3320 Storage, and the error messages only occur for this 2 faulty storage systems. It is true that mirroring will still created sucessfully regardless the error messages, however after error messages, I/O speed for that disk will be reduced.

Correction to my previous post: the "burn" button is not visible when browsing through the music library, only in the "purchased" or "playlist" views (which is really confusing, by the way.)
that's normal. you'll only see it in a playlist of some description. (the "Purchased" list is a playlist.) see:
I'm having trouble burning a CD or DVD
is that a home-built or custom-built PC? (checking, because it makes a difference when going checking for updates to drivers and whatnot.)

Can't Mount External SCSI to USB Drive

Hi guys- I currently have a problem involving an external scsi to usb drive that I can't mount. I tried the usual commands, fdisk -l, mount, lsblk, to discover the device but it's not showing up in /dev.
I ran lsusb -v and one section shows "mass storage" and since I don't have any other mass storage devices attached other than my /dev/sda, my guess is that this is the device. Below is the output of lsusb -v, how can I use this info to get this device mounted?

I'm using the latest kernel. The device is a macally Hi-Speed USB 2.0 external drive enclosure. Yesterday my BIOS was detecting it, and later that night I actually mounted the device with mount /dev/sdb1 /mnt/drive_2, I fired up the computer today and it's not there anymore, not in BIOS, not in the OS. This thing is acting very buggy and It's starting to scream hardware issues. There is a blue light on the enclusure that tells you when everything is okay, but now the light is red. Plus I can't hear the drive spinning.
arobson- I tried your suggestion and ran udevil monitor and a message popped up "Monitoring activity from the disks daemon. Press Ctrl+C to cancel." Then I plugged in the drive but I'm not sure what's supposed ot happen. I didn't get any messages after that.
Sorry to waste your time on this one guys.

Scsi emulation and parallel port printers

I'm attempting to get a Microtek ScanMaker V300 installed on my laptop. I've read the man sane-microtek2 but have great difficulty interpretting man pages at the best of times.
I have a port listed as /dev/parport0 at 0x378, or /dev/lp0 but no /dev/scanner or /dev/sg(x)
Being hardware illiterate I'm at a loss. Seems to have something to do with scsi emulation ??. Just how is the device created.
Any help appreciated (BTW Kernel 2.6.17 sane synced up to date).
The file /etc/sane.d/microtec2.conf exists in the filesystem.
Where to start?
Richard

Mixed news - I have solved one problem only to discover another!
Here's how I managed to get KDE adding printers again:
# pacman -Rd cups libcups
# rm -r /etc/cups
# pacman -S cups libcups
But I find that I cannot scan reliably with the HP PSC 500, getting either a "busy" or "i/o error" message when running XSane; or else it usually loads with scan resolution = 0 instead of 75. But sometimes (say 10%) it works!
I also found the sane-troubleshoot program from http://www.meier-geinitz.de/sane/sts/ and it reports:
[hpaio] failed to open scan channel: scan/sane/hpaio.c 665
<-- sane_open (hpaio:/par/PSC_500?device=/dev/parport0): Device busy

Also, I wonder whether this comment from http://www.xs4all.nl/~ljm/SANE-faq.html#43 is significant:
7.7. I'm using IDE over SCSI and I keep getting IO-error under xsane.
The IDE via SCSI driver seems to create problems. Please advise the mailing list.
Just checked again, and I can scan fine with the HP PSC 500, running from the Knoppix 5.3.1 live DVD.

External SCSI Disk Array problem

I am using a quad MacPro, 3 GB RAM, 10.4.11, ATTO UL5D SCSI card and an external U320 SCSI disc array. In the last few days I could not copy bigger then 3-6 GB files to the external SCSI storage, from the internal drives or from the an external firewire drive, because the system stalls and I have to restart the system using the power on button.
Any idea what can be the probelm? I checked the SCSI cables, termination, reseated the SCSI card, etcm but the problem remained.

First thing I would do is make sure your data and volumes are fine and run Disk Warrior.
Second, check that you have the latest ATTO drivers and firmware.
Are you using Apple Disk Utility, SoftRAID, or something else?
Can you rule out problem being with FW disconnected, or other PCIe cards?
Last, unrelated, up the memory to 4 x 1GB or more. What Apple recommended for Final Cut, symmetrical memory, or quad-channel,

SCSI Emulation for IDE Tape Devices

Linux has a nifty driver called ide-scsi.o, an SCSI emulation for IDE devices, that allows SCSI commands to sent to IDE devices. These IDE devices (CDROM, tape drives, etc...) appear as SCSI devices.
Does Solaris have something similiar?
Thanks,

I have tried burning without setting scsi emulation but give me some errors, so how can I set scsi emulation for burning CD/DVD on k3b???
It's in rc.conf by adding "ide-scsi"???
I'm using Kernel 2.6.4 (IDE version), KDE 3.2.1 and K3b 0.11.6.
Note: I've tried to upgrade k3b from 0.11.6 to 0.11.7 with "pacman -Su k3b" but say to me that already in last version - 0.11.6.
with kernel 2.6 you don't need anymore scsi emulation for cd burning, i do that, on the bootloader ( lilo is what i use) i add at the append line this --> hdc=ide-cd , and that's all, maybe even that is not needed, not sure. If you want to test if that works open a shell and type --> cdrecord --dev=ATAPI --scanbus
It should show your burner.
For k3b you maybe need to run the setup program first, and make sure your cdrdao is uptodate.

External SCSI CD-RW on G4 APG

This is about a Power Mac G4 450 APG, Mac OS X (10.4.8), 896mb RAM running 10.4.8.
This is a hand-me-down that I am reworking for use by my 6 year old daughter. The system has the original 20 Gb ATA HD and I installed an ATA 30 Gb slave HD and an internal SCSI 3.5 Gb HD off the Apple SCSI PCI card. I also updated the internal ATA 100 Mb Zip drive with a 250 Mb zip. All work fine as is.
However, I would like my daughter to be able to assemble her own iTunes playlist from songs on her CDs and then burn the playlist onto a new blank CD to listen to in her room (computer is in the house office so she will not be surfing by her self). I have an Ultra II SCSI external Yamaha CD-RW burner that I would like to attach to the system to allow this.
Unfortunately, any time I hook up ANY external SCSI device to the SCSI card, the boot up sequence stops and a dark box appears in the middle of the monitor. I’ve tried disconnecting the internal SCSI HD from the PCI SCSI card and just using it with any external SCSI device with out sucess. I’ve changed the SCSI devices SCSI ID and that does not help. Also reset PRAM, NVRAM and PMU with no luck.
Anyone have ideas??
Thanks,
DJ

One more thing to check is the termination on that external drive....it may be one of the kind that has a switch to enable termination on the back of the device or it may need a seperate terminator attached to the SCSI port not taken by the cable....I have always had the best luck (not sure why but it seems to be true) if I attach the cable from the computer to the top SCSI connection and the terminator to the bottom connection.
Cheers.

External SCSI???

Finally upgraded my SE FDHD to 4mb of ram. Problem is the external scsi (lacie joule 730mb) I got off ebay is giving errors OSErr ect. on LILO 7.56 and Anubis 2.54. It formats but can't copy any stuff. Just get disk error. And pathced Apple HD SC Setup will not verify the drive.
Is there any program that does low level format on system 6 or 7. And if not can I replace it with a 36gb like this. Or not so even if I partition the **** out of it.
http://www.ebay.com/itm/Apple-IBM-36GB- ... 816wt_1344

Kavan,
Let's start with a basic question. Where in the world are you and what resources do you have available to you?
If you are in the US and near a large city and you can find a mac user group and there is some old timer that has parts laying around, you might be able to find what you need. Otherwise, you need to find a computer recycler in a large city who will watch for items for you.
Forget trying to format the 36gb drive. I cannot even get the older macs to see the 9 gig drives that I can still buy. The machined want to see 4 gig or smaller.
You may have tor try several versions of Drive Setup to find one that recognizes the lacie drive. Mount Everything is some third party software that would see just about any drive, thus the name of the software company.
Post back with a little more information about a city near you. If ebay is your only source for older stuff, you will have to advertise. Vendors are not going to pay to list such dated equipment without some serious disclaimers about fitness for you configurations.

Scsi-emulation

A couple of newb questions:
1) what is scsi -emulation and why does XCDRoast need it?
2)do i need to setup scsi-emulation for all cd burning apps or are there any apps that will work without it?
3) how do i setup scsi emulation?
Thanks for the help in advance,

well after you have all the .wavs setup in the directory you will be burning from that command should work except instead of "something" use the "*" wildcard. for example:
cdrecord dev= "ATAPI:0,1,0" gracetime=2 fs=4096k driveropts=burnfree,noforcespeed -v -useinfo speed=52 -dao -eject -pad -audio /home/dk/music/*.wav
the * means, of course that anything that ends in .wav will be burned.

Why can't I boot from an external scsi drive?

In a previous post, I mentioned that my hard drive died. While trying to find ways to work around it, I dug out an old 4 GB SCSI drive I used to use with my old Mac, and hooked it up. When I booted from the OS 10.3 install disk, I was aboe to install the OS on the external drive, and choose it as the startup drive before rebooting. When I rebooted, however, the Mac could not see the SCSI drive as a startup drive. I tried it several times, changed the SCSI ID, erased the drive and reloaded the OS, repaired the directory with Disk Warrior, all with the same results.
What am I doing wrong?
Dave

What model SCSI card do you have installed? Some cards are driver-based, like the Adaptec 2906. Its driver is loaded from the boot drive, as the extensions are displayed across the screen during the startup process. As such, drives connected to that type of card can't be designated as the boot device. A newer SCSI card that's firmware-based, like the Adaptec 2930, can be used for booting the computer. If you have a card that's firmware-based, then you may need to update the firmware with a newer (Mac OS X) compatible version.

External SCSI HD setup problems - HELP

Hello out there in cyberland (especially T.B) --
I have had GREAT success in the past getting help on this forum (i.e. T.B.).
I have installed an Adeptec Ultra PowerDomain 2930 SCSI controller card in a PCI slot in a G4 MDD computer running OS X 10.4.11.
The controller card was purchased new and contained a CD that was supposed to assist in getting the external HD "up and running."
Even though Adaptec says this particular card and software will run on this computer and the OS contains an extension (Adeptec 290x-2930.kext) for the controller I have been unsuccessful in getting the HD operational.
The Adaptec card shows up in the System Profiler but the HD does NOT show up anywhere. I think (?) the HD should show up in the Parallel SCSI portion of the System Profiler. I turn on the HD BEFORE starting the computer and have checked the HD SCSI termination and cable setup. I have the HD SCSI ID# set to 0.
The SCSIProbe (v. 5.1.1) and PowerDomain Control (v. 5.0) located on the packaged CD both open a window stating they will not work with "Classic."
I have downloaded SCSIProbe v. 5.2 from the Adaptec site and it opens the same window. There is mention of a SCSIProbe v. 5.1.2 in the Adaptec help discussions but I was unable to find it on their site to download it.
Adaptec would not answer my written (email) calls for help or even whether or not the card will work under OS X. However, their specifications state the system will work as I have it configured.
I would appreciate any help that you folks are willing to provide.
T.O.M

Hi,
The Adaptec software you mention is only for OS8.6-9.2, not for OSX. Do you have Jaguar or Panther also installed on the same machine? If so, if you boot into Jaguar, do you see the HD in Apple System Profiler? Have you tried setting the HD SCSI id to something other than 0?
I recently had a similar issue w/an Adaptec 29160 and an HP tape drive. Everything worked fine in Jaguar. The Adaptec card not only showed up in Apple System Profile (ASP) in Jaguar (10.2.8), but the specific version of the firmware and driver were reported correctly. The same card in Panther (10.3.9) also showed up in ASP, but the firmware and driver version nos. were not reported correctly, but rather just binary addresses were displayed. Under Tiger the same card also only showed these binary addresses in ASP for the Adaptec card's firmware and driver version nos. The backup software did not work though under Tiger. I had to swap the Adaptec card for an ATTO SCSI card. Then the backup to the HP tape drive worked again.
I'd look to see if the SCSI HD you have has drivers specifically written for Tiger and see if installing them will result in the HD being detected.
Good luck!
Ed

External SCSI RAID drives not mounting

I have an ATTO UL3D RAID that was working fine and I updated to the recommended 10.3.9 Apple update and now my drives are not mounting on the desktop. They show up in Disk Utility and I can initialize them, but I have some important data that I want to rescue. I followed all of the suggestions from ATTO but nothing. Can anyone please help? Thanks.
G5 Dual 1.8 Mac OS X (10.3.9)

Mine take a very very long time to mount then they will not sleep even when unmounted. The firewire driver in Mavericks needs some work. If at all possible, I would use USB until the driver get's resolved.
