Raid Admin Cannot Find XRaid

I have a G4 XServe running 10.4.11 and an XRaid divided into 2 partitions, both raid 5. Recently the second partition disappeared. The problem is that Raid Admin 1.3.3 cannot find the raid. We are part of a large network, where none of the IT people speak Mac. I have found out that the Raid IP is a 169.254.x.x address and our XServe is on a different VLan and Subnet.
Question 1: I have one Cat 5 cable going to the top controller and a fixed IP for the correct VLan and Subnet, how do I change the IP on the XRaid without being able to see it in Raid Admin?
Question 2: Do I need a separate IP and connection to administer the bottom controller.

Hello, Dennis Goff, and welcome to the AppleBoards,
+Question 1: I have one Cat 5 cable going to the top controller and a fixed IP for the correct VLan and Subnet, how do I change the IP on the XRaid without being able to see it in Raid Admin?+
You can't. Without RAID Admin access your only control over the box comes from things like resetting and rebooting from scratch.
Can you clarify what you mean by "correct VLAN and subnet" here? Do you mean 169.254 or correct for your company's infrastructure?
You need a machine on the 169.254. IP range which is self assigned - essentially "no IP". The easiest way to do this is to attach a notebook set to DHCP directly to the RAID and it will self assign 169.254 as well and then the RAID Admin will be able to search and find it. Whatever IP range the ports are on you will need a machine that can speak to that IP range to communicate with it. The 169.254 range is not accessible from regular assigned IP ranges because it is reversed for special use. Note that the RAID Admin software is Java and will run on virtually anything and does not need to be on the Xserve.
+Question 2: Do I need a separate IP and connection to administer the bottom controller.+
No, a single ethernet connection is enough for complete RAID admin. The other ethernet light will be yellow in RAID Admin instead of green but if that doesn't bother you then don't bother.

I can't use Raid Admin connect to Raid

Hi All,
i can't use raid admin connect to my Xraid.
network is ok, networkcable is ok.Raid works find.
when i use raid admin connect to Xraid, it shows me"connection error" and then the app take more than 50% cpu usage.
any ideas?

Hi Chris,
If the controllers are not properly seated in the RAID chassis, they will not be able to communicate with RAID Admin and you will get a connection error. Improperly seated controllers can lead to other problems as well, so I would recommend reseating them.
To do this, power down the RAID by pushing the power button on the back and holding it for about 5 seconds. The RAID will not power off completely, but all the indicator lights on the front of the chassis should go out. Once those lights are out, unplug both power cables. Release one of the controller cards by pushing inward on both clips, then pull the card about half way out. Push it back in gently until both clips click into place. Do the same with the other controller card. Plug both power cords in and push the power button to power the RAID back on.
You should either unmount your RAID from your server, or power the server off before you power off the RAID. You can power your server back on once all the indicator lights on your RAID show green. If you have just unmounted it, it should mount automatically once the RAID controllers are up and running.
Hope this helps.

Raid Admin Not Connecting

I've left my comuputer and Xserve Raid running as advised, and went out of town for a week. It has been totally inactive. Today I opened Raid Admin and nothing happens. It doesn't search, there isn't a log etc. I added system and typed in the address, it searches but does not connect. However I am able to use Raid with FCP, and can open and play QT's that are on it as well as open other files. Should I just re-start the computer? It is connected with ethernet cable. Nothing has changed except the fact that I haven't touched anything in a week.

It doesn't have to be a G4 powerbook, it can be any Mac with RAID admin installed. I think the only reason he mentioned a powerbook was that most have their RAID connected in another location of the building and it is easier to access by walking down the hall with a laptop instead of lugging their desktop into the server room. Your current setup should work. Although you shouldn't have to ping the RAID because if you're on the same subnet, Raid Admin should find it automatically. If you have a router or switch or hub, maybe try to connect that between you and the RAID and see if Admin will pick it up. Then proceed to give it a static IP and you should be all set.

Warning lights on XRAID but RAID Admin won't mount it.

I have 3 Final Cut edit suites sharing 2 x 7TB XserveRAIDs.
I had an audible alarm on one of my RAIDs an amber flashing light by the System Identifier Button.
Edit 2 started up fine and my editor was happily working away. I then went Edit 2 to mount the RAID storage - made up of 2 x 7TB XserveRAIDs each split into 2 partitions providing a total of 4 volumes creating my volume based SAN. As I tried to mount the RAIDs using SANmp I had real issues. Eventually got the volumes mounted but then had the greyed out screen of doom when I tried loading up a Final Cut Pro project and had to do a forced shut down.
Edit 2 was still working but I then had similar problems in Edit 1 - not able to mount partitions and unable to load projects.
I tried looking up the RAIDs on the RAID Admin Tool but I'm only seeing 1 RAID when I should be seeing 2. The AID that is mounted is not giving me any errors which makes me think I've lost communication with the RAID with the problem.
Should I just shut the whole system down and hope it starts talking to me again when I fire it up again?
I just want to get on an edit my show.
Thanks.

William: Thanks for your reply, but you seem to be wide of the target here.
RAID Admin can connect to the RAID,
but doesn't see drives?
No. I can run RAID Admin on the Xserve or on a separate laptop, and either way RAID Admin can't find any RAIDs to show in the list of available RAIDs. So it doesn't even get to the stage where it can see any individual drives, since it doesn't find the RAID unit in the first place.
The red light you're seeing, as well as the
fact that Disk Utility can see all the drives
as individuals,
Clarification: Disk Utility is showing symbols for drives, but of course these are really partitions of the RAID, not the individual physical hard drives in the RAID.
indicates that either stuff is set in JBOD mode
... well I'd love to report what mode it's in, but RAID Admin won't show me . However, judging by the fact that there's no part of the file system that's obviously missing, (and also by our original intent when this was set up) I'm 99.9% sure it's in some redundant mode, and 99.8% sure that is simply in default RAID-5 mode.
or something is seriously wrong...
... depending on the meaning of "seriously"!
I'd guess the RAID set (and any data that
was on it) is gone.
... though as I noted in original post, it's in everyday use, including by me, and I've not detected any missing data, aside from a handful of files (out of total approx 2 million files) that return read errors.

I use PATA HD create RAID 1 on 6728,but Win2K cannot find HD,WHY??

I use 2 PATA HD,want to create RAID on 6728,but Win2K cannot find the HD,WHY????

You must install Promise RAID Controller driver for Win2k then only you can see it.
Read this Moan Guide is very important.

RAID - cannot connect Raid Admin

For whatever reason my network settings got altered today, and ever since i have been unable to see the Xserve raid in Raid Admin. I have put the ethernet settings back to the same settings it had originally but no luck.
No lights of any colour, and a message saying connection error. So i restarted, and now there is nothing in my Raid Admin at all.I have the option to Add System...but i have no clue about the info that is required!
Any suggestions please?
adam

Well, if you know the IP addresses, you can enter this in the Add System field.
If you don't, and it has dhcp enabled on one of the controllers, you cn connect with a direct cable.
If both negative, and you know at least the IP range, you can do a ping sweep and find the address.
Hope this helps

Raid Admin 1.5 - Recognize Array button not active

Hi all,
just updated to RaidAdmin 1.5, updated firmware on both controllers to 1.5 version.
I have 6 disks on which should be my lost array. Suddenly 'Recognize Array' button in utilities is not active.
Any idea?
Leos.

ok. The whole story:
Few month ago, I had RAID 3 schema on 6 disks. I did firmware update on my XRaid. This update WAS SUCCESSFUL. After XRaid restart, I lost my array. I didn't have backup. After unsuccessful local Apple support, I tried 3rd party companies to reascue my data. Noone helped me. I managed help from Apple in US, I sent my disks to them (quite expencive, I am from Czech Republic.). They recovered raid set on my disks to RAID 3 schema on 5 disks only - don't understand this. So I called them back a and I sent disks again, with detailed desription how it must be. Thay sayed OK and sent me back 6 disks, with no raid set schema - 6 unassigned to any array. And as a bonus, one of them was failed. So, now I have 6 disks, Apple claims, that raid schema is on disks (but i cannot see it on my raid - I realy tried everything - swapping possitions, controllers, cables .....). So when Raid Admin 1.5 brings this new function - recognize array, I started thinkink, that I have one more chance to recover my data back. But situation is as I described in first topic....

RAID Admin and Disk Utility show different sizes

Hello all,
I have tried searching through these forums for a resolution to this, but did not really find one. Here is my situation:
I have an XServe Dual G4 in a branch office. It has attached to it an XServe RAID. Last week, when I was down working in the office I added a new drive to the RAID. The lower channel on the RAID had 4 172GB drives in it, and I added a 5th and and told RAID admin to resize the RAID.
The next day, the RAID was finished resizing. RAID admin was reporting that the array was now 690GB. However, after rebooting the server and RAID multiple times, Disk Utility in OS X is still showing that the Volume on the RAID is only 517GB.
So, I have a couple of questions:
1. How is it possible that by adding a 172GB drive to a RAID 5 array that was about 520GB I ended up with an array that is 690 GB? That would imply that there is no parity (since 690 - 520 = 170 and the drive I added in was 172GB).
2. How do I get the server to see the additional space? The server is at the newest version of the OS and the RAID it as the newest version of the firmware.
Please help.

I've run into the same issue with a newer PPC XServe. However, after I tried to reformat, I still only show up with the orginal size, and not the new size, even after I restarted the server and XRAID.
Did you have any success with your reformat?

RAID works, RAID Admin stopped seeing it...

...but yet I can monitor my remote G4/RAID just fine.
I'm running 10.4.5 on a G5 Xserve/RAID, 10.3.9 on the G4.
I tried shutting the whole mess down, disconnecting and restarting, tried plugging the ethernet cable directly to another G5, etc, but the RAID will not show up at the IP address it was given. Was there something in Tiger that messed up my monitoring capabilities or changed my monitoring IP address? Is it possible someone tinkered with something they shouldn't have, and if so, how do I get it back without halting production in the whole shop?
Or is this just another one of those problems I seem to be the only one to have??
Xserve G5/RAID Mac OS X (10.4.5)

No, it happens. Just happened to me last month. RAID is fine - admin would show me three yellow lights and one red light and then would "gathering information" forever and ever with the spinning wheel.
First off - do you have matching firmware versions in your RAIDs?
I was told in no uncertain terms by Apple that running different versions of RAID admin than firmware version would result in the disconnect. If you have different versions of firmware you might want different versions of RAID admin.
Second - to fix I had to turn the RAID off AND unplug cables for 30 seconds and then restart. Notice Apple doesn't call it "off" they call it "power stand-by mode". To turn it off you need to unplug it or the machine stays in stand-by mode looking for the network signals.
Third - if you're just not finding the RAID could it just be on a different network IP range? There are a couple ways to find it if it's missing where you expect it to be.
1) Start RAID Admin and click "Add System" - if it is in your IP range it'll show up.
2) Run Network Utility. Ping 255.255.255.255 and you will get a response form 127.0.0.1 (that's you) and if another IP address shows up that's another device - probably the RAID if you're connected directly or on a local hub.
Remember - there are 2 ethernet ports with 2 separate NICs and that 169.254.a.b is the default range of the RAID IPs. If it's not where you expect it to be I'd start there. Make sure you are connected to the one you think you set - or use a hub to connect to both simultaneously for double the scanning pleasure. Also you should check that your subnet mask is set to something generous like at least 255.255.0.0 to make sure you're casting a wide net when you search.

RAID Admin - all green lights - controllers reset - RAID Admin still empty.

Hi there,
I am having huge issues with an Xserve RAID, it is connected to an Xserve on both fiber channels, the IP is not known however the range is, the controllers have been reset, the servers have been restarted. RAID admin is still not picking up the array. How do I do an IP sweep to check for the IP address? Is there a Terminal command I can use?
Thanks for you help in advance.

hi
connect a laptop directly to the xraid
if dhcp is on the xraid interface, they will find eachother when you start xraid admin and add system.
a sweep is done with ping. Say the range is 192.168.0.(1-254) you do a:
ping 192.168.0.255
this gives you all the devices which want to reply to ping.

Upgrade from server 10.4.11 to 10.5 cannot find OS

Greetings all,
I have an Xserve running 10.4.11 and I am trying to upgrade it to 10.5. When I run the setup assistant it initially doesn't see the OS RAID partition (two 500GB drives, RAID level 1). If I open the disk utility and select the parent of the RAID partition, the disk becomes visible in the select target screen, however after it runs through the installation pre-calculation I get a message telling me that the setup assistant cannot find OS X on the installation target.
I am at a loss here, the mirror is healthy and works properly but I cannot get the installer past this point.
The only offhand thought I have is that it might have something to do with the RAID version--Disk Utility tells me that the mirror is "Version 1.0" and gives me the option to update to version 2.0) but even after several hours worth of searching I can't find any information on this distinction and I am not about to try it if there is a chance that the upgrade still fails and I'm left with a 10.4 install that cannot boot.
Any thoughts or ideas would be immensely appreciated, thanks in advance.

I had similar problems upgrading same configuration even after converting to version 2 RAID sw.
I think I cloned boot drive to non RAID ext. drive, did the upgrade and cloned back to freshly in 10.5 configured RAID 1 setup.
Your milage may vary. diskutil (man diskutil) can be used to convert RAID v1 ->v2.

HP LaserJet P4015TN - Windows 7 cannot find on network

Several months ago we started to get random print jobs with garbled characters that would come out from time to time. Over time, these events became more frequent and the number of pages printed out increased as well. Sometimes a whole try of paper would be printed out with these garbage characters on each page.
Unplugging the network cable would stop this but it would start up again immediately after plugging the cable back in. Initially I thought this was a network issue so I swapped cables. No luck. Swapped ports. No luck. Reset all of our switches and our router. No luck. Removed the print driver from our machines and reinstalled. No luck.
I left it unplugged for several days and the random printing finally stopped. Problem solved! Well, not exactly. The random printing issue is now gone but now I cannot install this printer on any Windows 7 machine. In fact I cannot find the printer either by entering the IP directly in the setup or by browsing the network.
The odd part is I can ping the printer and I can login to the admin page via the printers IP without an issue. The other oddity is that this is only occuring on Windows 7 machines. XP machines can print to the printer with no issues.
I have tried this on various machines with the Windows Firewall on and off and antivirus software on and off. Nothing seems to make a difference.
However, I did have success using the HP Print and Scan Doctor software. It did finally see the printer and let me install the HP Universal Print Driver. I can now print to the printer using this driver. This is not the prefered way of doing this as we have many public users of this printer that would not be technically savvy enough to setup printing this way.
My question is, why did this printer stop connecting to Windows 7 PCs? Nothing has changed on our network. Is there a know issue with a Windows Update that is causing an issue? I am symied with this.
Any ideas?
I finally came to the conclusion that this had to be a bad network board.

You can disregard that last line that states this was a bad network card. An HP service center determined that the card is fine and found nothing wrong with the printer.

Windows 7 Backup "The System cannot find the path specified" - Error Code 0x80070003

I'm having severe problems backing up my own machine to a share on our
FILE-SERVER as \\FILE-SERVER\Backup\
I have already backed up another PC successfully using exactly the same settings I have used on my own PC. So I presume it is nothing to do with the
FILE-SERVER or the Backup settings. It has to be something to do with what I'm trying to backup from my machine.
First some background.
This exercise all began when the Windows Server 2008 r2
O/S fell over on one of our Servers. I tried reinstalling the O/S several times, without success. In the end I grabbed another drive and re-built the O/S. I then had problems promoting it to a Domain Controller on the network.
In the end I renamed the Server from FILESERVER
to FILE-SERVER.
We routinely share four folders on what is now
FILE-SERVER:
\\FILE-SERVER\Backup
- a Folder where backups from all other machines are written, so that they will be backed up with the Server
\\FILE-SERVER\Company
- holds all our Company data
\\FILE-SERVER\GEM
- this is the application folder for our own database
\\FILE-SERVER\Install
- holds all Install files for the software we use
These are all held on a RAID 1 Array that is separate from the System Disk that fell over.
Prior to the Server falling over, I had Backup working fine on my machine.
On my Notebook PC I had made these shared folders 'Available Offline', so that I still had everything available to me when I was out of the office. They were
of course shared as \\FILESERVER\... not \\FILE-SERVER\...
Having got the Server up and going again, I began to get the Backups from the Windows 7 Client PC's going again.
I started with a Desktop, which of course did not have any Offline Files.
That proved relatively straight-forward.
I then started with my machine. Initially I did not make the above shared folders 'Available Offline'. I set up my Backup using exactly the same settings that
had worked OK on the desktop machine. But when I ran the backup I got:
The System cannot find the path specified, Error Code 0x80070003
I tried all sorts of things to get it to work:
I restored the system to the earliest point possible,
I ran chkdsk,
I defragged the drive
All to no avail, so I tried backing up:
with and without a system image,
reducing the backup to a single folder,
a single Folder with only one .txt file in it,
making the Folders 'Available Offline' again.
Nothing made any difference.
In the end I looked in the Sync Center to look at the Offline Files Folder.
Under Mapped Network Drives I discovered I still had the Files and Folders from
\\FILESERVER. In their Shortcut Menu 'Always Available Offline' was greyed out. So I deleted the Offline Copies. This deleted the Files in the Folders but not the Folders.
Since I could find no way of deleting the old Mapped Network Drives, I decided I'd painted myself into a corner by renaming the Server.
So I bit the bullet and re-installed my Notebook too. This did get rid of the unwanted old Mapped Network Drives - BUT NOT THE ERROR!!
I’ve been through all the troubleshooting procedures in:
http://social.technet.microsoft.com/Forums/windows/en-US/629597bb-7be0-455c-b81e-a149472d3f9b/windows-7-backup-the-system-cannot-find-the-path-specified-error-0x80070003?forum=w7itprogeneral
Method 1
It had none of the symptoms reported in
http://support.microsoft.com/kb/973455
but I scanned for ‘reparse’ points anyway. Found several “Junction Points” but none that were “Mounted Volumes”, just ordinary ‘File Folders’.
Method 2
Check a drive for errors.
Looked at:
http://windows.microsoft.com/en-us/windows7/Check-a-drive-for-errors
Checked
both boxes. I closed machine down, to check for errors when it re-started.
It didn’t seem to find anything.
I say seem, because I did not actually see it finishing checking the empty space, but stages 1-4 found no problems and Windows 7 restarted normally.
It did detect 66 ‘Reparse’ Points, which is more than it found when I scanned for them earlier.
Method 3
Yes, I am an administrator or my own machine and, as such, I have ‘Full Access’.
I downloaded an ran the Process Monitor, filtering for Process Name “Wbengine.exe”, but did dot get a single event.
So I’m not sure what’s going on.
HELP - I'm out of ideas!
I have a WORD Document that documents all the Settings I've used on both the Server and the Clients, together with the reasoning behind those settings, but
I cannot find a way of uploading it.

I am having the exact same problem with Windows 7 Professional. Out of the blue, this issue just started a few months ago when running my monthly Windows Backup where I have used a USB drive for the last 3 years, and never ever had this issue before. Most
of the solutions listed on the Microsoft websites and answers deal with
"Restore" functions, not the
"Backup" itself. I have 3 folders being skipped during the backup.
So I went and changed the Backup from "let Microsoft choose files, directories, etc" to "Let me choose". I included the files and folders that were being skipped, and ran the "Backup" again, and got the same error message,
but the files that were skipped the first time were "Backed up" finally. This issue is somehow related to my "Libraries"?
The 3 backup problems are:
Backup encountered a problem while backing up file C:\Windows\System32\config\systemprofile\My Audio Books\Audio Book Recordings. Error:(The system cannot find the path specified. (0x80070003))
Backup encountered a problem while backing up file C:\Windows\System32\config\systemprofile\My Audio Books\Audio Book CD Label-Cover Art. Error:(The system cannot find the path specified. (0x80070003))
Backup encountered a problem while backing up file C:\Windows\System32\config\systemprofile\My Audio Books\Audio Book MP3 Tag Art. Error:(The system cannot find the path specified. (0x80070003))
Did a "checkdisk" - no problems. Ran a program to fix registry - no problems. All updates up to date. I guess I could eliminate these folders from the Backup folders in the
Library, and just choose them under the "Users" locations, and be done with it. But I really want to understand this, and fix it. This is within Windows 7 and may be related to Windows Media Player or
some recent Windows update. Thanks.
