MSA2000 Configs and Volume Mapping

[Mohamed Darweesh]

Hi All,

I have the following Hardware Specs:

1:HP StorageWorks MSA2312fc Dual Controller Array
3:HP MSA2000 3.5in Dual I/O 12 Drive Encl
48:HP MSA2 450GB 15K rpm 3.5 inch SAS HDD

I have decided to create two RAID 50 Arrays each RAID 22HDD+2hot spare.

So Vdisk#1 has 22 active HDD + 2 hot spare HDD with total size =9TB has one volume called SAN01_Server01 and mapped to Server01.

Vdisk#2 has 22 active HDD + 2 hot spare HDD with total size =9TB has one volume called SAN02_Server02 and mapped to Server02.

one Server01/02, I can see the new mapped volume using fdisk -l command i.e. /dev/sda.

however Can anyone send me the procedures for how to complete the mapping on the Servers?

Servers running RHEL ES 4 Update 8 64bits.

I hope an answer will avilable ASAP.

Best Regards
Mohamed Darweesh


then created only two volume one volume/vdisk.

Sounds like all you need to do now is partition the drive from within the operating system and format the space so you can use it...

The If you can see the disks on the appropriate servers... your mapping is completed.

Thanks Steve, having some difficulties to partition 9TB harddisk, could you please send me the procedures on the Servers to complete the formating and partitioning?

when tried to partition the harddisk using this command fdisk /dev/sda

the maximum partition size is only 183GB I can see. strange!!!!

You have to find out if "RHEL ES 4 Update 8" is able to deal with SCSI LUNs larger than 2 TeraBytes.

If it does, you need to deal with a partition mechanism that can describe disks larger than 2 TeraBytes (MBR-style partitions can't do that):
