Unit policies

Several unit policies are set when you create a new unit:

Write Cache (enabled, by default)

Read Cache (Intelligent, by default)

Drive Queuing (enabled, by default)

Ignore ECC (Continue on Source Error When Rebuilding (disabled, by
default))

StorSave Profile (Balanced, by default)

Auto-Verify (enabled, by default)

Rapid RAID Recovery (enabled, by default)

The particular policies that you can adjust when you create the unit vary,
depending on which program you are using: 3DM2, 3BM, or the CLI.

You can change all of these policies after the unit has been created, with one
exception. If Rapid RAID Recovery is disabled, it cannot be enabled later.

For a summary of what these policies do, see the discussion under “Setting
Unit Policies” on page 100. For how to
adjust each one, see the procedures
later in this chapter.
