Confuguring raid5


Hi

You would need 4 Hard disk drives in total. you would need to create 2 RAID 0 (striping) and then Mirror them (RAID 1). to elaborate, HDD A&B will be at RAID 0 as well as HDD C&D. after, you would have to Mirror your two RAID 0. (raid 0+1 is also known as raid 5)

Hope this helps.

The system is setup using the RAID 5 config, now out of 5 drives it says 'OK' for 3 drives on 0, 1 & 2 and for 3 & 4 it says 'Replacement'. Is there any way of finding the correct Logical sequence...


Dont you have any levelling inside the machine? Go open and check.

When you have replaced the 2 defective drives with a new one, restart the computer and Raid 5 will automatically rebuild.

I have hp proliant with raid 1+0 .I have 2 hard and usr in option


Sometimes shortened to RAID 10, RAID 1+0 is a particular combination of two different RAID levels: mirroring (RAID 1) and striping (RAID 0). The appeal of RAID 1+0 is simple: mirroring gives you the highest level of availability RAID offers, with the fastest rebuild times when a disk fails; while striping - using the proper chunk size - is the basis for high-performance I/O.

About SCSI


Replace the hard drive with a drive that is the same type and the same size, or larger. It will rebuild itself.

By same type I mean that the connector on the back of the drive and the speed of the drive interface must be the same. If the new drive spins at a different rate it will not create a problem, except that if it is slower it will make read/writes slower. If it is larger it will only use part of its capacity, matching the capacity of the other drives.

Note that if you were to replace all drives with larger drives (one at a time) the capacity of the entire array would be the same as the original. If you want a larger array it must be built from the start with that larger capacity.

Take out the bad drive. If you can get the exact same drive, do it, otherwise look it up on the manufacturers web site to find out size and type.

While there are a few possible RAID configurations that you could be using on that server, the chances are overwhelming that it is RAID level 5 that you are using. This RAID level is tolerant of a single drive failure. If you lose another drive before your new drive rebuilds your data will be lost. Hopefully you have a backup.

RAID 5 stripes the data and the parity data across all available drives and when a drive fails, the missing data is rebuilt on the fly from the parity data. When a replacement drive is installed the parity data is used to rebuild the data that belongs on that drive. The advantages of RAID 5 are fault tolerance (of a single drive) and speed because each drive only has to provide or write its portion of the total data being accessed or written.

Problem with creating array


The Perc RAID controller in a 2600 doesn't support RAID 4.
You can do RAID 0, RAID 1 and RAID 5.

With 3 HDD's your best bet would be a RAID 5.

Mirroring is RAID 1 (which would only use 2 of the drives)

Drive array problem


Hi Nick ,

As of now you can Select "F2" to accept data loss and re-enable logical drive. This Load OS Normally .
It seems that one of the HDD in the RAID 5 has failed , Did you notice any LED indications like red or amber on the HDDs ?? if so get that hdd replaced . Make sure the Failed HDD is replaced .
You can run the Array Diagnostic Utility from HP System tools to check the Failed Drives and also frimware version of the controller . If the frimware is not latest Update it from HP website. DL380 G4 should have Smart Array 6i controller .

Hope This was Helpful
cheers :)
