Using the ATF Driver with VxVM
CLARiiON ATF driver and DMP co-existence is supported in VM 3.0 and above.
For DMP to co-exist with the ATF driver, the CLatf package (Application Transparent
Failover Driver for CLARiiON) must be installed before the VRTSvxvm or SUNWvxvm
packages are installed on the system.
Note In VxVM 4.0, ATF/DMP co-existence works only with the CLatf 1.3.1, 3.1.0, 3.3.0.3
and 3.4.0.7 packages.
For DMP to co-exist with the ATF driver, the boot disk should not be under control of the
ATF driver.
You can make DMP co-exist with the ATF driver. To do this, use the procedure that is
appropriate to your situation.
◆ If VxVM is not installed, do the following:
a. Install ATF.
b. Install VxVM.
◆ If VxVM is installed with DMP currently enabled, do the following:
a. Prevent or suppress DMP.
b. Install the ATF driver.
c. Install VxVM 4.0, if appropriate.
d. If DMP is not re-enabled, re-enable it now.
◆ If VxVM is installed with DMP currently prevented or suppressed, do the following:
a. Install the ATF driver.
b. Upgrade VxVM 4.0, if appropriate.
c. If necessary, reinstate the DMP settings.
