3. echo "1" > /sys/class/scsi_disk/0\:0\:x\:0/device/rescan
for ubuntu use echo "- - -" > /sys/class/scsi_host/host#/scan (find host # with ls)

4. parted /dev/sdx

Model: VMware Virtual disk (scsi)
Disk /dev/sdd: 322GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Disk Flags:

Number Start End Size Type File system Flags

(parted) quit
Information: You may need to update /etc/fstab.

5. lvextend -L+xG /dev/(lvm logical volume)
There is an easier way to do steps 2 and 3. Install sg3_utils (RHEL and clones) and run as root:

Code:
rescan-scsi-bus.sh -s

Yep - that works >90% of the time including when doing SAN HBAs. However, on rare occasion it doesn't so knowing the echo method is beneficial.
