ql-dynamic-tgt-lun-disc - Scans for newly added LUNs. SYNOPSIS
ql-dynamic-tgt-lun-disc [OPTIONS] DESCRIPTION
Dynamic TGT-LUN Discovery Utility This utility scans for newly added LUNs. After adding new LUNs, you do not need to unload, then load the QLogic FC driver or reboot the system To begin scanning the LUNs issue following command: # /usr/sbin/ql-dynamic-tgt-lun-disc -al, --allow-lip LIP is not issued by default, even if it is required for scanning new LUNs Setting this option, allows the utility to issue LIP. -cl, --current-luns Displays LUNS currently present -e, --extended-scan Use this option as "-e | --extended-scan". to rescan LUNs. This will identify any change in attributes of existing LUNs. This option can be used in combination of scan/refresh or max luns -h, --help, ? Prints this help message -i, --interactive Use this option to use the menu driven program -is, --iscsi Use this option to operate on ISCSI HBAs, this option can be used in combination of any other supported option. -m, --max-lun To set the maximum LUNs to be scanned -p, --proc Use PROC file system for LUN scanning -r, --refresh To refresh, that is remove LUNs that are lost use the options "-r|--refresh". This will remove the LUNs which no more exist. -s, --scan [ -r|--refresh ] The QLogic LUN scan utility re-scans all the devices connected to the QLogic HBA SEE ALSO
