EMC Symmetrix Storage Array
The Linux SCSI subsystem finds multiple instances of the same Logical Unit Number of an attached EMC Symmetrix storage array.
Add the kernel boot optionscsi_mod.dev_flags=EMC:SYMMETRIX:0x20240to theINITRD_MODULESparameter list in/etc/sysconfig/kernel. After saving the file, runmkinitrdto create a new initial ramdisk. The parameter will become effective on the next boot of the system. To apply the changes to a running system without a reboot, run as userrootthe command echo 'EMC:SYMMETRIX:0x20240'>/proc/scsi/device_info and then rescan the SCSI bus by executing echo '- - -'>/sys/class/scsi_host/hostX/scan (replace the"X" in "hostX" with the number of the host adapter.)
