Discovering new LUNs on Vertias with FC

After you create a new LUN and map it to the Linux host, you can discover the LUN by using the SCSI rescan script.

Before you begin

You must have a copy of the rescan script.

The rescan script is available with the sg3_utils package. In addition, the rescan script is available with Red Hat Enterprise Linux 5 Update 4 or later, Red Hat Enterprise Linux 6 and 7 series, SUSE Linux Enterprise Server 10 SP2 or later, and SUSE Linux Enterprise Server 11 and 12 series.

For earlier versions, use the vendor-specific rescan scripts, which are available on their web sites. See HBA vendor-specific documentation.


  1. Rescan the operating system: /usr/bin/
  2. Initiate a rescan of the operating system device tree from the Veritas Volume Manager: vxdisk scandisks
