Hi,

How can I run command to check existing Linux (Centos 4.x)RAID controller type model and disk qty, etc.

Thanks in advance.

You can find out the raid controller information with the command lspci. When a disc is detected in the system it will create a device entry which you can find in /dev as /dev/hdX or /dev/sdX where the hd entries are the IDE drives and sd entries are the SCSI/SATA drives. Each drive partition should appear as /dev/hdXN or /dev/sdXN where N is the partition number and X and the drive entry. in my system, the currently active drive entries (I run CentOS/RHEL 5) are:

/dev/hda /dev/hdb
/dev/sda /dev/sda3 /dev/sdc /dev/sdd1 /dev/sdf /dev/sdh1 /dev/sdj /dev/sdk1
/dev/sda1 /dev/sdb /dev/sdc1 /dev/sde /dev/sdf1 /dev/sdi /dev/sdj1
/dev/sda2 /dev/sdb1 /dev/sdd /dev/sde1 /dev/sdh /dev/sdi1 /dev/sdk
