6.8 Phantom Controllers Under RAID
Manager 6.22
There have been issues regarding the installation and configuration of Solaris with
RAID Manager 6.22 and VERITAS Volume Manager. These issues regard instances of
"phantom controllers" or device nodes. This can cause problems for your installation.
To avoid these issues perform the installation of your system in the following order:
1. Solaris:
a. Install Solaris.
b. Install required patches.
2. RAID Manager 6.22:
a. Run pkgadd to install the RAID Manager 6.22 packages.
b. Edit the rmparams file and change the line
"System_MaxLunsPerController=8" to the number of LUNs needed.
c. Run /etc/raid/bin/genscsiconf.
d. Edit the rdac_address file to configure how you want your LUNs distributed
over the controllers as well as to define which path the system is allowed to
“see”. Refer to the man page rdac_address for further details.
e. Run init 6.
3. Configure LUNS:
a. Run /etc/raid/bin/rm6.
b. Upgrade firmware (if needed but perform offline).
c. Set controller active/active (if needed).
d. Create LUNs.
4. VERITAS Volume Manager (VxVM):
a. Run pkgadd to install the VxVM 3.0.2 packages.
b. Run vxinstall to create a rootdg.
c. Run /etc/raid/bin/rdac_disk.
d. Run init 6.
