Adding newly created LUNS dynamically

ssma12 · 04-13-2010, 01:33 PM

We are running Oracle 10.2.04 RAC on Red Hat Linux 5 and when ever our SAN storage admin created new LUNS we have to reboot the servers so that server can see newly created LUNS. This causing downtime to our application. How we can add LUNS dynamically without rebooting servers. We are using device mapper mulitpath from red hat version 0.4.7-30.el5 and we have QLOGIC HBA's.

Qlogic provides utilities for this purpose.

You can go to:
http://driverdownloads.qlogic.com/QL...I/default.aspx
to see what downloads are available for your card/Linux distro. Once you go to the next page just search for "scan" and you should see the dynamic scan utility they provide.
