Referring from kb.vmware.com/kb/1016106
Quote ".....However, MSCS LUNs that have a permanent SCSI reservation cause the boot process to lengthen as the ESXi host cannot interrogate the LUN due to the persistent SCSI reservation placed on a device by an active MSCS Node hosted on another ESXi host."
Question
1. After setting--perennially-reserved=true, Exsi host would beable to interrogate the lun?
2. What interrogation is the ESXi host doing to the lun?
3. Before setting --perennially-reserved=true, is the ESXi waiting for some timeout?
