I am getting logical disk on host twice

I have configured a MSA1500. Created an Array and also created one logical disk then I have configured the SSP with enable and select host for that one logical disks. But when I am looking into host at Computer management in Disk management option, it is showing the disk from MSA but instead of one logical disk, it is showing two disk, when i am going to initialize both of the disks. Computer is giving me error for disk2 but disk1 is initialized. I am worried about that why two disks are displayed instead of one ? Rohit

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?

Can a raid5 be expanded to include an additional disk on the dac960prl or must the raid be destroyed and re-created?


Hi,

As a rule of thumb, a raid 5 array can be expanded to include additional drives. This is done during the boot process and then going into your RAID controller setup. You would then go into the RAID configuration and add the new drive to the array. This was the simplified explanation but i think you get the idea.

Things to consider,
DO NOT remove the RAID array unless you dont care about losing data.
DO NOT try to add a smaller drive than what is currently part of the array.
When possible, the new drive should be identical to the existing drives, but I have added same size, same speed more than once and it will work.
All of the drives you want as part of the array must be on the same controller.

Hope this helps,
Brian

A well meaning~idiot teenager changed my set up on my Dell Dimension in BIOS to Intell ARRAY.. now I cannot bring Windows up


If the well meaning teenager took a non-raid configuration and created a RAID array, then any data on the drives was destroyed.

If you reply with the RAID array and HDD status information from the boot screen (THE intel Raid Controller will report the status of the array, degraded, normal or Failed and the status of each HDD member or non-member disk.) With that information I MAY be able to assist in getting the system to boot

Trying to create a server using the ASRock k7vt6 mobo


turns out the RAID enable in the bios is also used to enable the SATA. but this doesn't mean you have to use RAID to use SATA drives! there's a separate bios to configure the RAID that you can access after the initial boot screen by pressing tab. here, you can delete an existing array or create a new one. deleting the array makes the motherboard see both drives separately, like I wanted. problem solved :)

Not getting a drive letter from Compaq SCSI RAID setup


Did you see any new drives in the disk managemen screen? To get to the disk management, hold window key down and hit 'R', then type diskmgmt.msc and hit enter.

If you do see the drive in the lower half of the screen, you need to initialize the drive either as dynamic disk or basic disk. Then you need to add a new partition and format it.

Good luck.

Run Compaq Array Configuration Utility


Hi Foambob,

Try all means to get a smartstart CD.
Normally new version will be able to use on older hardware , but no guarantees.
I have always found it easier to use smartstart CD auto mode.
You can also do the install and then run ntssd to update all the drivers etc., but I don't recommend it for novices. Use the auto mode , it takes longer but safely and surely.

Good luck

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 :)

Problem with new array.


Do you see your new disk in the "Disk Management" window? To get there go to "run", type "compmgmt.msc", then click disk management. If you do see the disks there, then you need to format the disk to a "basic" configuration. If your new disk/volume does not show up there, I would suggest a hard reset on your server whenever possible. I see this issue at times with Windows and newly added storage array logical drives.
