21.14.2. Resizing an iSCSI Logical Unit

After modifying the online logical unit size, re-scan the logical unit to ensure that the system detects the updated size. To do this for iSCSI devices, use the following command:
iscsiadm -m node --targetname target_name -R[7]
Replace target_name with the name of the target where the device is located.

Note

You can also re-scan iSCSI logical units using the following command:
iscsiadm -m node -R -I interface
Replace interface with the corresponding interface name of the resized logical unit (for example, iface0). This command performs two operations:
  • It scans for new devices in the same way that the command echo "- - -" > /sys/class/scsi_host/host/scan does (refer to Section 21.12, “ Scanning iSCSI Interconnects”).
  • It re-scans for new/modified logical units the same way that the command echo 1 > /sys/block/sdX/device/rescan does. Note that this command is the same one used for re-scanning fibre-channel logical units.
