RAID Admin Parity verification test: How to use?

Folks:
My basic question: How to get "Parity validation" test to tell you something useful.
XServe RAID, dual 7x250, RAID Admin 1.5.1 and firmware updated 2 weeks ago.
After rebuilding a RAID array, I ran the RAID Admin's Parity verification test (which I assume probably just runs a test built into the firmware?).
My expectation: That this test would
a) change nothing,
b) report details on any problems.
What I got when it finished was this in the log:
Lower Controller 04/23/07 01:22:35 Data Was Lost During A Rebuild Operation
Lower Controller 04/23/07 01:22:35 Data Was Lost During A Rebuild Operation
Lower Controller 04/23/07 01:22:35 RAID Set 1 Verify Complete (-200001)
Lower Controller 04/23/07 00:14:13 RAID Set 1 Verify Started
What the heck?
a) I didn't ask for a rebuild operation.
b) How do I determine the extent of validation failure (maybe this is what "data was lost" refers to?)?

Can I use rebuild parity data in raid admin with these conditions?

4 disks in array, one went bad, replaced disk (same type of disk). Light on slot is red but in raid admin its says in event log that disk 2 is online, but when I select the drive to check info on that drive it says disk not installed. If I use the rebuild parity data function will it only rebuild the data from the 3 disks?
will disk 2 be recognized?
It seems I am getting conflicting info from raid admin and indicator lights on disk slot. I took the drive back out checked connections and rebooted the xraid.
I thought the array would rebuild itself when the new drive was inserted, am I missing something?
Thanks

Sometimes you have to go into the RAID utilities and use "make drive available" option.

How to set up email in RAID Admin?

Using RAID Admin 1.5.1, I need to know how to set up the it up for automatic email notification. Okay I got as far as clicking the Email icon adding my .mac address. Now what do I put under SMTP. It's asking for the "server" and the "from email address". Our company uses a Microsoft Exchange server whether or not that means anything. And what is up with the check box for SMTP Server Authentication?
Thanks for any input. I appreciate it!
jeffrey

Thanks Donald for answering my question. I found the IP Address of our exchange server and I plugged that into the server field. And I plugged my own company email address into the "From Email Address" field. That didn't do it, so I plugged in my network username and password into the authentication fields. I clicked "Send Test Email" again. Still didn't work. But here is the key in case anyone else has problems. At least in my case, I had to click the "OK" button to verify my settings. Once verified, I went back into the email settings and clicked "Send Test Email" again. Voila! A test email ended into my .mac email account right onto my iPhone within 1 minute. I think this is so cool. I can be away from the office (whether I be skiing or golfing) and be notified instantly if one of the components start to fail on our Xserve RAID system. Awesome!!!!!!!

To test how can we use the opt 'logical file name' to name the file based

Hi Sir/Madam,
to test how can we use the opt 'logical file name' to name the file based on the selection made in the dtp run for extracting data as flat file.

Hi Vishali,
In the DTP select the file location as application server and give the logical file path. The actual file and logical path can be created using transaction "FILE" and "AL11".
Rest of the process is same as that of extraction from local file.

Durgesh.

Hi,
BW Quality Testing
We have not used any tool like Mercury Quality center for testing. In our case we created some test scripts and based on that we proceeded further.
All the testing is done in quality before moving into Prod.
Testing like Integration and unit testing are done in quality.
You need to test if the extractions are working fine, data is getting loaded into targets, post load activities like activation, rollup, compression etc are successful etc.
We test the PC chains also in Quality.
We schedule / trigger the chains and monitor them. We ensure that all the process types are happening successfully.
One major area we concentrate on is to identify decencies in the chain. This will ensure less errors and also reduce chain timings by a great extend. Dependencies should be kept to a minimum wherever possible.
Also in cases where we use events/third party scheduling tools to trigger BW chains we check that out.
Executing reports to check the definitions are correct.
The volume of data will be lesser in Quality compared to prod.
Also activities like Change runs, Deletion, Selective deletion etc are done.
Almost all the activates in Prod are done in Quality.

Idea about how-to using 'Agilent Wireless Test Manager' interfaces in Labview ?

Hello everyone,
I am not sure whether it is appropriate to post this here.
Currently I got a Wireless Test Manager CD(Agilent E6560A) and is trying to convert some functionalities inside class 'cdmaTXMeasTests' into labview.
I am doing the 'code domain power testing' module with labview, which is well done in that 'cdmaTXMeasTests'.
I am wondering if any one could provide me some idea how to use that 'cdmaTXMeasTests' in my labview without rebuild the wheel.
( I am not sure whether that would work, Are the libaries used by wireless test manager a ActiveXDLL that could be used by labview ? Or there is some other way to do it or not?)
Any idea is well appreciated,
+Kunsheng Chen

Good Afternoon Kunsheng Chen,
It seems like you are trying to port your DLL. Rather, I would suggest using a Call Library Function Node (right-click the Block Diagram, Functions>>Connectivity>>Libraries & Executables>>Call Library Function Node).
From the Agilent website, this is a C dll so you will be able to access it using this VI in LabVIEW with no problems. You might want to contact Agilent to see if this DLL has ActiveX components. Alternatively, you can simply browse the list of ActiveX components on your computer.
The following links may provide some useful information for using a DLL in LabVIEW.

RAID Admin logs problem -- how to avoid 2-day truncation?

Folks:
I have a problem that appears to have started about April 5 when I updated RAID Admin and Xerve RAID firmware to latest versions. Since then, I'm only seeing last two days of entries in the log (ie: what you see in the "Events" tab in RAID Admin). Strangely, entries up to to April 5 are preserved.
Of course I did't notice this until some was already lost. But now I want to fix it. I don't see any setting for "max log length" or similar.
Further more, I could use an explanation of where this log lives -- is it something that RAID Admin retrieves from the RAID box, or is it somehow preserved on the computer running RAID Admin or what?
Thanks,
Graham

Simply? There is no simple way.
But if you will accept a way that is not so simple, there is a company that sells a product that allows you to run a Java class as a service under NT. I don't remember its name but it has been named several times in the past in answers to this same question. A search of the forums would probably find it.

How to map LUN via Raid Admin?

i want to map a LUN used by a ESXi 5 server to another 2 ESXi servers but I could not find option for it on Raid Admin 1.5.1

It's been a while, but I seem to recall that LUN masking was removed in version 1.5.1 for unknown reasons.
If you can roll back to (I think) RAID Admin 1.5.0 you have the option to use LUN masking, but 1.5.1 doesn't have it.

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.

How to use rescuecd to access NAS200 RAID drives

I have been lurking trying to figure out how to access my NAS200 drives after a power supply failure and of course I have no backups, relying on the RAID to create my two copies. (Lesson learned)
I have a NAS200, with two Western Digital 1TB Green hard drives. They are configured in a RAID 1 mirror and they are in a journaled file system
So from what I've been reading, I believe they are in XFS. and I can use the rescuecd iso to access the drive directly to copy them off onto another drive.
I am using Windows XP SP3. The computer system is 8 years old - a Dell Pentium 4 Dimension system with 4GB of memory. I do have Ubuntu, but I have no idea how to use Linux, and definitely not the command line that the rescuesystemcd drops me into.
I've taken one of the drives and installed it in an external USB drive and plugged it in the system.
In Windows XP SP3, I can see the drive on my virtual file manager and I can see the three partitions, one main data partition, the configuration partition and the swap partition, but of course it's not the right file system. and it's not ext2/ext3 so Ext2IFS will not work for me from what I've read.
In ubuntu 11.10, when I've plugged in the external drive, I have no idea how to access the drive. I suspect I have to mount it, but I have no idea how to do it or even where to begin looking for it to access it.
And of course in the CLI using the systemrescuecd, I am completely lost there: The last CLI I used was MS-DOS from over 15-18 years ago. I can ls (MS-DOS dir) and cd to navigate the folders of the file system and I believe cp is copy? and if I was using the Ubuntu CLI, I have to sudo everything I believe.
So after this long post, what am I asking for?
- How do I mount the external drive in either Ubuntu or the system rescue CD iso.
- Can I mount a second external drive with a NTFS file system in Ubuntu or the system rescue CD?
- I would prefer to do it in Ubuntu or some other graphical method so that I could just drag and drop from one disk onto another or failing that using the commandline, what command would copy the entire drive's file system from one to another?
Thanx

Are you able to access the web interface of NAS200 using its IP address? If, 'yes' then unplug both the hard drives? Reset NAS200, reconfigure it and connect the drives again. See if that helps.
