Hi,
I've an HP ML350 G9 server that has a failed logical drive, this logical drive was setup RAID 10 and I can only see from the log (see below) that there is only one failed disk why am I getting the "Logical Drive 3 has failed and cannot be used. All data on this logical drive has been lost" the RAID 10 should recover till 2 failed disk drives?

can you please help?

Details:

Smart Array P440ar

Hi,

I have the following errors on my Adaptec Raid.

ad Block discovered: controller: 1 ( Adaptec ASR7805 #3A12130E4B0 Physical Slot: 6 ), channel: 0, deviceID: 6, WWN: 5000C50063A0CF6D, vendor: ATA, model: ST4000NM0033-9ZM, S/N: Z1Z0J8VH, firmware level: SN03 starting lba:7fffffff end lba:7fffffff, bad block recovery possible.

Failed drive: controller: 1 ( Adaptec ASR7805 #3A12130E4B0 Physical Slot: 6 ), channel: 0, deviceID: 6, WWN: 5000C50063A0CF6D, vendor: ATA, model: ST4000NM0033-9ZM, S/N: Z1Z0J8VH, firmware level: SN03  0 Last Failure Reason: .

Please also see the attached files.

I wanted to find out if this is to be expected a normal error that is corrected by allowing the raid array to rebuild.

Or should I be concerned and replacing the hard drive ASAP.

Also if I do go for the replace and it is still in warranty is this type of error sufficient that Seagate would replace the drive?

Thanks,

Ward.

Is there a way to connect a SAS hard drive to (preferably external) USB A or some other way to format it as a stand alone drive / wipe it / etc?  NOT trying to read data from when it was in a server / connected to raid controller, etc.  Looking to start new with the drive.

I have something like this for SATA.  Looking for something like this but for SAS:

https://www.amazon.com/StarTech-com-USB3S2SAT3CB-Drive-Adapter-Cable/dp/B00HJZJI84


I'd rather be able to connect to the external USB, but would you think this would work?  The description says 'Allows you to connect a SAS hard drive to a SATA controller that supports SAS drives'.  Any idea if most dell optiplex desktops support sas drives?

https://www.newegg.com/Product/Product.aspx?Item=N82E16812200431
https://www.amazon.com/StarTech-18-Inch-Cable-Power-SAS729PW18/dp/B000V72AQ4

Reading the reviews for that item on amazon , it seems no, desktops don't handle SAS drives.

So what's the cheapest SAS controller and is there one that connects via USB?  Yes, totally not what SAS is inteneded for (many drives, RAID). I am just looking to be able to wipe / format / write new to it as a JBOD... and bunch being one : )

what is the recommended stripe/full strip size for a Raid 10 configuration exclusively for SQL 2012 files which used for electronic  transaction authentication

Walked into a new site.  There are two Virtual Drives set up, and both show as functioning.  But on the 01 Virtual drive only, it shows 3 Foreign Drives on the Perc H710 Controller and one other as ready.  The local person(not Technical) has assisted the previous Tech to add two additional drives recently (i believe after one was already marked as Foreign).  I removed the two that she added when she said she did not do anything after inserting the drives.  Can I clear the config?   Will it affect the working Drives or just Clear the Foreign Config from that one Drive?

Server 2008 R2. keeps rebooting while trying to load windows.
When i start the server, it says, starting windows and restarting itself

i checked the raid in raid storage manager. it looks good. status is bootable.  and from bios, i can see the harddisk as the first priority to boot.  so i dont think it is an hardware issue. i did memory diagnostic test. no issues found. further, i tried to boot from single harddisk - still same issue. and when i plugged back the second harddisk, raid went to rebuild ? is does not mean i will lose data , right ?

think its something to do with software side. tried to boot from safe mode, same issues. keeps rebooting. dont have a previous versions to restore.
i never did repaired a server. any ideas to do repair or to work around this issue.  ?

I wish to purchase hard disks for purpose of storing financial tick-data. As per my calculations, 6 TB will be required for 3 months of history. Beyond that I may later decide to keep deleting if I don't need or to buy additional storage if I certainly must store longer history.

I do not want to risk losing any of the latest 3 month historical data due to hard disk failure, that is why I intended to set-up RAID 5.

My question is: Which hard disks should I buy?
My constraints/doubts are:
1)  I don't wish to spend money on SDDs, it's hefty price is not worth the additional read-write speed for my purpose.
2)  I immediately want to buy just one hard disk to take one time data load from someone, but want to make sure I can use this hard disk later (in a matter of  weeks)  when I do end up buying other hard disks, and whatever else hardware is required to set-up RAID etc.
3) Will setting up RAID 5, using say four 2 TB HDDs give me 6 TB of storage?
4) Will this RAID system necessarily need a container (rack) and cooling ? Any recommendations for a cheap but reliable rack if so?  
4) I need the hard disks to be easily removable and mobile (not crash due to speed bumps on road), because I might need to, say once a month, take one out and transport it locally to get it loaded etc.  (can one even do that with a RAID 5? i.e. take out one disk, get more data on it and put it back in the rack and expect all disks to magically "get that data"?)
5) I am not sure whether I…

Does the attached solid RED light that stays on forever just mean the OS RAID partition is working and I should NOT eject the drive ?

If not, what does it mean since both of my PHYSICAL servers have the same 1st drive in the RAID as solid RED that stays on forever ?

I have an SBS 2008 Dell server that will not boot up. I get to the screen to boot normally, safe mode or last known good. Each one continues to boot then the mouse cursor shows and then the server reboots. It is in a loop.

I went to safe mode with command prompt and ran chkdsk /R but that did not fix it

Server is Dell T610 with RAID 5.

What can I do to get this server back up
