'hpsa' - A SCSI-based Linux device driver for HP Smart Array Controllers

Logical drive size expansion is not being recognized or updated in the operating system.

Solution

The cciss driver communicated directly with the block layer to inform it of size changes in the

underlying logical disk devices. With hpsa driver, one must execute a manual refresh

command to alert the SCSI layer that size information has changed.

For example, after increasing the size of a logical volume using Array Configuration Utility,

use the following command on RHEL 6 to force a rescan of the device size:

echo 1 > /sys/class/scsi_disk/C:B:T:L/device/rescan

(replace C:B:T:L with the controller, bus, target, and LUN number of the affected

device)

You can use the command cat /proc/partitions to view the size information before

and after to verify the rescan process.
