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.
root@hostname% cat /etc/redhat-release
Red Hat Enterprise Linux Client release 5.4 (Tikanga)
echo "- - -" > /sys/class/scsi_host/host0/scan
% dmesg | grep -i hd
