Installation Procedures - for all MSA1000 Deployments
When installing or updating the HBA drivers, always use the drivers and the
installation scripts provided on the MSA1000 Support Software CD and the
MSA1000 website.
Your MSA1000 will not operate as intended if you update your HBA driver
manually or use drivers obtained from the HBA manufacturer.
After installing your MSA1000, remember to set your host mode to identify
your operating system to the MSA1000.
If you need to install Secure Path software, be sure to follow every server
reboot prompt that is presented.
Failure to acknowledge a server reboot prompt may result in your path
redundancy not functioning properly.
Be sure to reboot your server after the server portion of the install and again
after the client portion of the install.
