IBm x3650 with EXP3000
Any chance you put the drives in the trays 'backwards'? It will still fit in the box but not connect to the backplane. -
ServeRAID 6M - Windows 2003 - Disks re-synch ALWAYS on failover...
It is supposed to resync on failover. This is done to insure data integrity. When failover occurs, the controller taking control of the other nodes logical drives cannot know if all the stripes are coherent. If there are incoherent stripes (parity doesnt match data) and a drive subsequently... -
why won't my SCSI drives come out of stanby ?!?!?
1) Are they spinning up? 2) Are they formatted 512bytes or something else wierd? -
SeveRAID 6i in PC
5i and 6i as well as 8i are called ZCR or Zero Channel RAID controllers. They have to be used in a unique slot which has logic to reroute interrupts from the motherboard storage controller to the ZCR card as well as prevent the motherboard storage controller from being seen by the host... -
IBM 4MX Raid controller failed. Advice please.
Is the card in a hotswap PCI slot? The battery can fail in a way that will cause the hotswap slot to power off due to overcurrent and prevent the card from being seen. -
Converting Raid 0 Array to Raid 1 IBM Server
Using ServeRAID Manager, go to physical device view. Click on the 'array' which is your single drive RAID 0. Right click and select Logical Drive Migration. Is migration to RAID 1 provided? Make sure your extra 'ready' drive is present. The case for single drive RAID 0 may not have been... -
Converting Raid 0 Array to Raid 1 IBM Server
Not enough information... It seems that you have created a 'single drive RAID0' and now want to add the replacement drive and convert this single drive RAID 0 to a 2 drive RAID 1. What server? What RAID controller? -
RAID 1 issues on HS 21
Can you provide more detail on the blue screen error message. Does it just say 'disk error'? Did you press F6 during test mode and supply a driver diskette? -
How should we rebuild an IBM server RAID 5
pull out the bad one (with the yellow light on) and replace it with the new one and the rebuild will start automatically. Thats all handled in the firmware instead of ServeRAID Manager. -
IBM RAID REBUILD FAILURE
That would be my concern too and may be validated by the fact that the OS wouldnt boot. You could have tried to force one at a time online and see if it would boot. If not, force off that one and force on the other and see if it would boot. -
IBM RAID REBUILD FAILURE
Did both drives fail at the same time? If so, boot the ServeRAID manager CD and bring them both back online and cross your fingers. -
Migrating an expansion unit from one serveraid card to another
Another ServeRAID 6M will import the existing arrays just fine. Its just like replacing a failed card in a machine. However... does the enclosure also include the boot volume?? Changing servers may result in a boot issue due to the HW differences between the servers. -
LSI 1064 Controller and Poor Write Performance - Cross Post
If this is simply an LSI 1064 without a companion IO Processor then it does not have a write cache or even the capability to have one. The 1064 is a SAS HBA chip with specialized FW to enable basic mirroring and striping. It is hardware RAID but its very primative hardware RAID. -
Upgrade 2x36GB to 2x140GB on x335
One thing you could do is 'break' the mirror and make the drives appear as two individual drives instead of a mirror. Use Partition magic to expand the first drive. Then recreate the mirror being careful to specify the expanded drive as primary. It will rebuild to the secondary and you should... -
need help to ADD disk in Current Raid 5 Array?
Click the Help button on the menu bar of ServeRAID Manager. Type "add capacity" into the search bar and click search. Select 'adding physical drives into an existing array' and it will tell you exactly how to do it. -
RAID 5 or 10?
Thats not a very large database. What is the stripesize? If its too small, you may be killing your performance. My gut would be to use RAID 5 with a 64K stripesize. Is most of the workload reads? Is this the only array in the box? Is the OS on the same array as the database? Do you have... -
Can we use regular SCSI drives instead of HOT-SWAP drives ?
Depends on what you mean by 'Regular'. SCSI drives come in two mechanical flavors... 68 Pin for non hot swap applications and 80 pin for hot swap applications. 68 pin drives have a separate power plug while the 80 pin merges the power into the SCSI connector. They are not directly... -
Swapping out a raid card
The metadata statement depends on which system and what RAID solution he has. If its a system with ServeRAID 7k (or 6i/6i+), then the metadata is the same as ServeRAID 6M (except perhaps if you have a RAID 5E array defined). Clear the config of the 6M and import the config of the driveset. The... -
Upgrade 2x36GB to 2x73GB Raid1 Array on LSI1030
Something you could try.... First, I assume you have the old 36G drives as backups... Break the mirror... ie go back to two single drives. Remove the second drive Use partition magic to stretch the first drive partition to fill drive. Add the second drive and reestablish the mirror... -
Upgrade 2x36GB to 2x73GB Raid1 Array on LSI1030
ServeRAID and the LSI 1030 do not have the same metadata. ServeRAID will just see two empty drives.
