They are two different things but you appear to be using them interchangeably. You can ask command to scan on hard disks with -C option i.e. Two key components of the storage stack are the Virtual Disk Service. Monitor components of HP EVA storage arrays like Virtual disks. With internal DAS, the storage disk/disks are directly located inside of a hosting. In HPUX, we have dedicated ioscan command to scan new hardware. With LUN to VM mapping, gain a comprehensive overview of your HP EVA 3000,4000,5000,6000. If these utilities are not available, you still be able to scan them from OS. If the disk is from storage array then there are chances you have storage vendor utilities/scripts available to scan storage on server example: evainfo (for EVA storage), xpinfo (for XP12K storage), powermt (for EMC storage). To let the kernel know that a new disk is made available to server disk scanning is required. This tree needs to be updated with new disk information.
The kernel has a know hardware tree with it. Once the disk / LUN is made available/visible to the server, the next step is to scan it. of a virtual disk to specific physical disk blocks through a dynamic map. If its a storage LUN then it’s masking and zoning at storage level to WWN of the server. Key EVA values Managing HP Enterprise Virtual Array Solution Overview Higher.

Hope this guide helps you with your EVA configuration and please post any comments or points for discussion. The EVA sustained substantial physical damage due to the flood water preventing access to the data.
