How can I check if these are alternate links. I don't have EMC power path or Veritas DMP. Just linux with 6 disk devices.<BR /><BR />TIA<BR />Shahul Fri, 27 Mar 2009 13:19:59 GMT https://community.hpe.com/t5/operating-system-linux/multiple-paths-to-disks/m-p/4389414#M35816 Shahul 2009-03-27T13:19:59Z https://community.hpe.com/t5/operating-system-linux/multiple-paths-to-disks/m-p/4389415#M35817 Edit /etc/scsi_id.config and verify that you have commented out:<BR /><BR />options=-g<BR /><BR />Get the UUID for the devices with:<BR /><BR />scsi_id -g -s /block/sdc <BR /><BR />The result of the command above represents the device's UUID.<BR /><BR />If you have two devices with the sam UUID, then they are multiple paths to the same disk.<BR /><BR />If you have Qlogic HBA, you can use the multipath feature of the driver.
