How to scan for disks with Storage Foundation for UNIX and Linux

When adding new disks to a Storage Foundation configuration, separate scans are required by the operating system (OS) and by the Storage Foundation application. This post provides information about the commands and procedures that may be used to scan for disks.

 

Commands that are used by Storage Foundation to update itself with information about devices that are visible to the OS

Command Description
vxdisk scandisks Refreshes the DMP device tree with information drawn from the current system device listings, updating devices that have changed and registering new, previously undiscovered devices.

Note: This command does not replace the need to scan for devices using the commands that are provided by the OS.

vxdctl <-f> enable
  1. Runs vxdisk scandisks.
  2. Sets vxconfigd to the “enabled” state, if it is not already enabled.

Note: Adding “-f” limits the rescan to new devices.

I have started unixadminschool.com ( aka gurkulindia.com) in 2009 as my own personal reference blog, and later sometime i have realized that my leanings might be helpful for other unixadmins if I manage my knowledge-base in more user friendly format. And the result is today's' unixadminschool.com. You can connect me at - https://www.linkedin.com/in/unixadminschool/
