"Unable to Detect Newly added HDD - Redhat 5"
Hi Folks,
I am unable to detected newly added HDD in my redhat-5 OS.
I am expecting to get /dev/sdb.

Following are the utilized commands or syntax.

Code:
root@hostname% cat /etc/redhat-release
Red Hat Enterprise Linux Client release 5.4 (Tikanga)

Code:
echo "- - -" > /sys/class/scsi_host/host0/scan

Code:
% dmesg | grep -i hd
SCSI device sda: 1951170560 512-byte hdwr sectors (998999 MB)
SCSI device sda: 1951170560 512-byte hdwr sectors (998999 MB)

Code:
root@hostname% fdisk -l

Disk /dev/sda: 998.9 GB, 998999326720 bytes
255 heads, 63 sectors/track, 121454 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1          13      104391   83  Linux
/dev/sda2              14        1288    10241437+  83  Linux
/dev/sda3            1289       20410   153597465   83  Linux
/dev/sda4           20411      121454   811635930    5  Extended

/dev/sda7           22961       23441     3863601   82  Linux swap / Solaris

root@hostname% cat /proc/partitions
major minor  #blocks  name

   8     6   10241406 sda6
   8     7    3863601 sda7

Even tried installing sg3_utils, but no use.

Code:
root@hostname% /usr/bin/rescan-scsi-bus.sh -c
Host adapter 0 (megaraid_sas) found.
Scanning SCSI subsystem for new devices
Scanning host 0 channels 0 1 for  SCSI target IDs  0 1 2 3 4 5 6 7, all LUNs
0 new device(s) found.
0 device(s) removed.

Please share your inputs.

Thanks
