It takes time. From the controller technology guide: When you create a RAID 1, RAID 5, or RAID 6 logical drive, the Smart Array controller must build the logical drive within the array and initialize the parity before enabling certain advanced performance techniques. Parity initialization takes several hours to complete. The time it takes depends on the ...

On modern hardware RAID controllers, RAID metadata is written to the disks, so they are somewhat portable, with restrictions on drive ordering; they have to be moved together. However, this is the wrong way to handle backups. Intentionally failing (groups of) disks and forcing a degraded array is fraught and a bad approach to accomplishing offsite backup. ...

HP ProLiant server hardware evolves throughout the lifecycles of long-running Operating System distributions like Red Hat Enterprise Linux. In your original post, I specifically asked what version of RHEL you were attempting to install. This is important information because Red Hat 6 was introduced well before Generation 8 ProLiant servers. There are ...

The error decode is Bh/4Bh/0Bh = ABORTED_COMMAND/NAK_RECEIVED. I wrote my own tool to decode these and try to give a basic assessment at http://scsi.ev-en.org/ These errors indicate that you have a bad link somewhere, most often it is a bad cable but it can also be a bad port on either side (drive or slot).

After some testing these seem to be both RAID-10 (even if both LD's look quite different regarding span depth and span size): Virtual Drive: 1 (Target Id: 1) Name :Virtual_Disk_1 RAID Level : Primary-1, Secondary-0, RAID Level Qualifier-0 Size : 2.725 TB Sector Size : 512 Is VD emulated : No Mirror Data ...

I've had to deal with 2 failed drive RAID 5 arrays, and the short answer is you have to send all drives which were part of the array out for recovery if you want to get that data back. It WILL cost you thousands of dollars, so it will be up to management to decide whether the lost productivity is worth the cost. In general RAID 5 will stripe data across ...

In an n-disk RAID5, you need n-1 disks to read back the data. If two drives are dead, no other disks will contain a full set of data and you have to resort to your backup. For speed purposes, data is striped over the disks to allow for faster reads.

It depends. There probably isn't a more specific answer without more specific information about the anticipated hardware setup, the RAID level, the quantity and type of disks, the reason for a failure, etc... I'd usually take a well-designed ZFS solution over a consumer NAS solution, but again, the details matter.

From this thread (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/618542): I found an answer to the ERROR: (0x03:0x0101): Invalid command opcode:opcode=0x85 problem: http://kb.lsi.com/Print16532.aspx : "This error can be safely ignored." What is happening is that the kernel is sending a scsi code 0x85 (which from ...

Rebooting will clear all rebuild progress and yes it will start over at 0. I had the same issue with the same card and other 3ware cards. Had to weigh the value of the current reboot versus waiting for rebuild again. I will admit, sometimes it was worth more to start over and other times it was worth more to wait for rebuild to finish. Depends on your use ...

The drivers are part of the kernel, they do not require separate installation. If there were no drivers, the disks would not even be visible on the system. Yes partition sizes will need to grow if the underlying storage grows. You should use LVM if you plan to do this, otherwise the system will need to be taken offline to grow the partition. /dev/sdxx is ...
