The “rescan-scsi-bus.sh” can be used to scan new LUNs in a CentOS/RHEL machine.
When ‘rescan-scsi-bus.sh -i’ is run, script execute as well a LIP_RESET (ISSUE_LIP) which may cause a disruption in I/O on the server and even cause an outage in case of a system running on heavy load.
Redhat says this type of scan can be distributive,since it can cause delays while I/O operation timeout and remove devices unexpectedly from OS.
So perform this scan when really you want to scan the disks and LUNS.
