Raid w/ hard drive defunct

It says there is a hard drive that is defunct however the system does boot up but the application does not work and I think it is due to the oracle not being able to run. How to recover from the data corruption due to the drive failure?

Re: raid w/ hard drive defunct

Well lets make some assumptions
1. You have a Raid 5 System
2. You only have 3 drives in the Raid ARRAY
3. Only 1 drive has failed

To fix the problem you should only need to Replace the Failed Drive
Then start the raid management software or bios
Rebuild the array

If you have more than 1 drive failed in a RAID 5, and still must recover the data it is possible. But very expensive. Still fixable however.

Re: raid w/ hard drive defunct

A RAID 5 array would still allow you to access and use the data with one drive having failed. So, since your application isn't functioning I'm assuming that you've lost more than one hard drive in a RAID 5 array OR you've lost both drives in a two drive RAID 1 array OR you've lost one (or more) hard drive(s) in a RAID 0 array OR you've lost a lethal combination of drives in a RAID 10 array. Any way you slice it you will have to replace the failed drives and restore the data from a backup. The only other "safe" option is "roll the dice" with a data recovery service (no guarantees of success) and (will be much more costly than it would have been to have an active backup system in place). You can always try to recover the data yourself; there are various techniques, none of which are safe and WILL make data recovery service less likely a successful option. Good luck!

IBM Server not detecting hard drives

You know i find this all very suspicious. For one thing a ups is designed to take the hit so it will get fried and your computer will be fine. Suspicious to me but not an answer to your question so i will try this. The new raid card was installed (might be off on this part, haven't kept up with this) were the hard drives and the raid assembly matched back up. IE raid 1, 2, 3 etc. Do believe they are up to raid 7 now. So if hard drives were not put back in the original position and and raid card setup for the original raid array you might have this problem. Hope this helps, but it's been a long time since i worked with raid arrays.

ServerRAID-6i Logical drv =1, Others=0 Firmware7.12.13,Status OK Warning:1 Logical drive(s) Offline Warning:1 Online drive(s) defunct

HI, It appears you may have a failed "physical" drive in your Raid set on the server. The system will run fine with one failed drive, but it is recommended to have the drive replaced by it's vendor, or vendor representative. If the 2nd drive in your raid set fails. You will loose your logical drive and all your data on this drive.
You may wish to confirm you have successful, recent backups, just in case another disk fails before your failed drive has been replaced.

In my IBM X226 server 2 HDD became unavailable in RAID 5 configuration. now I have replaced the hard disks and rebuild process is continuing. 1962 operating system not found error message is being shown...

Raid level 5 gives you some redundancy in your raid however it only allows you to lose one hard drive, two hdd lost would not permit to recover from. the parity bit can rebuild one hard drive but not two, sorry your raid might be lost

No SCSI Chips found on the adapter

This is a serious problem and you could easily guess wrong and blow away your data.
Good news is that Dell servers have lifetime support. Without a warranty you will have to pay for any parts you need but, if you are lucky, you won't need any. If you do get the part # from Dell and check eBay for it.
Get the Service Tag from the server and call Dell Technical Support.
You can get the phone # from their website.

Physical drives not found

I"t says one logical drive is offline and two physical drives are defunct."

sounds like RAID. Try booting up off of one drive. If there is no OS, try keeping one drive in the drive bay and see if you get a orange light then. like dereknewland said, could be the backplane.

Xseries 346 wont boot

You don't say whether or not your os is on the RAID 5 partition. Assuming that it is (for performance reasons, this is not recommended) then you should check to see if you have the option of configuring a separate raid configuration on your raid card (e.g. do you have a card with more then one RAID channel?) If this is so, I would create a separate RAID 1 array and install the OS just on that. Then you can mount the RAID 5 array with your data intact. Once you're up and running, you can remove the old OS partition, as it's no longer needed.

Defunct drive

You could rebuild the defunct drive with the raid program on your server.

i don't know your type and model of your server.

8488 or 8648 and the model 3 digits.

for this you need serveraid manager

please do not update your firmware or drivers at this point if applicable.

if rebuild of a defunct drive doesnt work you'll need to change the drive. remember in a raid 5 you need min. 3 drives.
