Question about HP StorageWorks MSA20 (0808736947138) Hard Drive Array

1 Answer

MSA with logical array of 6 250 GB physical drive... I replaced one of those drives with a 1 TB drive. It is rebuilding at the moment and identified the drive (box 1:drive 4) as a 1 TB drive. When it completes the rebuild, will it increase the size of the logical array by the size of the new drive without any assistance from me? I expect that I don't need to enter the ACU, do I? Thanks ... Earl J.

SOURCE: I am getting logical disk on host twice

Are you sure that our logical disk is not mapped twice to your host channel on your MSA 1500? If it isn't have you tried a power cycle to the storage array and a clean shutdown/restart on your host?

First off all,i do really like the concept of your website.It's a real good gimmick!
I had to replace the whole controller (which was defective) to get msa 1000 working.

I have a Gen 8 Hp server with 5No 600GB HDD. The first two disk are mirrored, the other 5 are on raid 5. 1 of the 3 on raid 5 is flagging amber colour. How do I replace the HDD without losing Data?


Before replacing drives • Be sure that the array has a current, valid backup. • Confirm that the replacement drive is of the same type as the degraded drive (either SAS or SATA and either hard drive or solid state drive). • Use replacement drives that have a capacity equal to or larger than the capacity of the smallest drive in the array. The controller immediately fails drives that have insufficient capacity. In systems that use external data storage, be sure that the server is the first unit to be powered down and the last unit to be powered up. Taking this precaution ensures that the system does not, erroneously, mark the drives as failed when the server is powered up. Replacing drives The most common reason for replacing a drive is that it has failed. However, another reason is to gradually increase the storage capacity of the entire system. NOTE: In fault-tolerant configuration, hot-plug hard drives can be replaced when server is ON, but in case of a Non-hot-plug hard drive, it should be replaced when server is OFF. For systems that support hot-pluggable drives, if user replace a failed drive that belongs to a fault-tolerant configuration while the system power is on, all drive activity in the array pauses for 1 or 2 seconds while the new drive is initializing. When the drive is ready, data recovery to the replacement drive begins automatically. For systems that support non-hot-pluggable drives, if user replace a drive belonging to a fault-tolerant configuration while the system power is off, a POST message appears when the system is next powered up. This message prompts user to press the F1 key to start automatic data recovery. If user do not enable automatic data recovery, the logical volume remains in a ready-to-recover condition and the same POST message appears whenever the system is restarted. Automatic data recovery (rebuild) When user replace a drive in an array, the controller uses the fault-tolerance information on the remaining drives in the array to reconstruct the missing data (the data that was originally on the replaced drive) and then write the data to the replacement drive. This process is called automatic data recovery or rebuild. If fault tolerance is compromised, the controller cannot reconstruct the data, and the data is likely lost permanently. Time required for a rebuild The time required for a rebuild varies, depending on several factors: • The priority that the rebuild is given over normal I/O operations (user can change the priority setting by using HP SSA/ACU) • The amount of I/O activity during the rebuild operation • The average bandwidth capability (MBps) of the drives • The availability of drive cache • The brand, model, and age of the drives • The amount of unused capacity on the drives • For RAID 5 and RAID 6, the number of drives in the array • The strip size of the logical volume • Firmware versions of the Smart Array Controller and Hard Disk Drive • Presence of BBWC/FBWC CAUTION: Because data rebuild time may go upto the rate of 200GB/15 minutes, the system could be unprotected against drive failure for an extended period during data recovery or a drive capacity upgrade. When possible, perform rebuild operations only during periods of minimal system activity. When automatic data recovery has finished, the drive status LED changes from flashing green to solid green. If the drive status LED on the replacement drive changes to flashing or solid amber, the rebuild process has terminated abnormally. If an abnormal termination of a rebuild occurs, identify the cause and appropriate corrective steps. Abnormal termination of a rebuild If the activity LED on the replacement drive permanently ceases to be illuminated even while other drives in the array are active, the rebuild process has terminated abnormally. The following table indicates the three possible causes of abnormal termination of a rebuild. Cause 1: An uncorrectable read error has occurred. 1. Back up as much data as possible from the logical drive. CAUTION: Do not remove the drive that has the media error. Doing so causes the logical drive to fail. 2. Restore data from backup. Writing data to the location of the unreadable sector often eliminates the error. 3. Remove and reinsert the replacement drive. This action restarts the rebuild process. If the rebuild process still terminates abnormally: 1. Delete and recreate the logical drive. 2. Restore data from backup. Cause 2: The replacement drive has failed. Verify that the replacement drive is of the correct capacity and is a supported model. If these factors are not the cause of the problem, use a different drive as the replacement. Cause 3: Another drive in the array has failed. A drive that has recently failed can sometimes be made temporarily operational again by cycling the server power. 1. Power down the server. 2. Remove the replacement physical drive (the one undergoing a rebuild), and reinstall the drive that it is replacing. 3. Power up the server. If the newly failed drive seems to be operational again: 1. Back up any unsaved data. 2. Remove the drive that was originally to be replaced, and reinsert the replacement physical drive. The rebuild process automatically restarts. 3. When the rebuild process has finished, replace the newly failed drive. However, if the newly failed drive has not recovered: 1. Remove the drive that was originally to be replaced, and reinsert the replacement physical drive. 2. Replace the newly failed drive. 3. Restore data from backup.

How do I rebuild broken RAID 1?


If Raid is broken then logical drive will fail & will result in data loss.
enter into Smart Array Controller bios by pressing F8 & Recreate Raid 1 by selecting two working drives.

My Mac no longer recognizes the drives


Raid 1 mirrors the disks, but they are still in an array. You need to identify which disk of the two failed. Replace the bad one and let the unit rebuild the raid if it can. This could take hours. Independently, I have not found them to work alone. They need the built raid array. I lost a ton of pictures on a 4 drive raided array that lost one drive, even though they were raided mirror.
Best bet is to see if your manufacturer will guide you through the diagnostics and procedures to restore the array for that unit.

It looks like you have two arrays here. The first one being a mirrored RAID array and has only one disk. This means that the other disk has failed in some sort. This does not mean that the drive is bad, just the RAID failed for some reason. You will need to rebuild the RAID if you want to maintain the same level of redundancy.

You can just attempt a rebuild the RAID to the same drives but if this fails you will want to replace the bad drive. In order to do this you will need to make sure you can tell which drive is which. You do not want to mirror the bad drive to the good one.

If attempting a rebuild to the existing drive does not work or is not an option (because the failed drive could really be bad), you will need to determine which physical drive needs to be replaced. You may be able to hot-swap the drive but if you can power things down, that is always safest. Once the new drive is installed, you can rebuild to it and all should be well after that.

A DRIVE RAID 0 VOLUME IS FAILING GENERATION 2


> RAID

Rapid Array of Independent Disks

RAID logically combines several identical disk-drives for better performance or for better reliability.

For better performance, one RAID configuration "stripes" the data, i.e., when you write a block of data, the block is split into "stripes", and each stripe is written to a different disk-drive.
Since each stripe is smaller than the whole block, it is faster to transfer the data in "parallel".

For better reliability, another RAID configuration writes each block of data _identically_ to multiple disk-drives. Thus, if one disk-drive fails, your data still exists on the other disk-drives.
You can then replace the "bad" disk in the array, and use software to "rebuild" this "mirroring" of your data, by copying all the data from one of the "good" disks onto the "new" disk.

So, in your case, one of the disks in your array is failing. Identify it. Replace it. Rebuild your array.

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 :)

Help please to restore the failed raid


Well if your data is gone at this point, you mines well just proceed with rebuilding a new RAID 5 set with your replacement drive. Even if one drive fails in a RAID 5 set, your logical drive should still be accessible. Goodluck.
