Note: ESS volumes 282, 283, and 284 are seen as LUNs 0, 1, and 2, respectively.
You can access the LUNs in Tru64 UNIX by using the following special
device files:
v /dev/rdisk/dsk3
v /dev/rdisk/dsk4
v /dev/rdisk/dsk5
Setting up the Tru64 UNIX device parameter database
Perform the following steps to set up the Tru64 UNIX device parameter database.
Note: For a clustered configuration, you must perform these steps for each
member in the cluster.
1. Quiesce the storage
2. Place the system in single-user mode.
3. Login as root.
4. Change the directory to /etc
5. Edit the ddr.dbase file to include the lines shown in Figure 28 on page 36 as an
entry in the disks subsection.
