Specifications

Figure 12 shows an example of the Korn shell script called essvol. Figure 12 shows
a summary that includes information for all the ESS volumes that are attached.
See Figure 13 for an example of what displays when you execute the essvol korn
shell script.
Note: ESS volumes 282, 283, and 284 are displayed 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
