42 Planning to Install and Configure Pathlight VX

Preparing for Early Tape Creation Settings

Table 30 assists in gathering information for Early Tape Creation (ETC).

• Maximum number of Physical Drives to use, the maximum value is equal to 1 less than the total

number of physical drives.

• The valid values for the Media Percentage parameter are percentages from 75 to 99. Specify the

percentage at which ETC initiates for the associated media.

•The Start Time and End Time values are times during which the system runs ETC, typically outside

of production hours. You can configure ETC to run all day.

Preparing for Storage Policy Settings

Table 31 on page 43assists in gathering information for Storage Policies. The table provides three columns

in the event that up to three storage polices will be set up. If you are setting up more than three storage

polices, you can duplicate this table as many times as necessary to provide for the number of policies you

are setting up.

•The Storage Policy Application window values for Start Time, End Time, and Days of Week

values specify the times and days during which storage policies are suspended.

• All Day (Y/N) means the Storage Policy should be suspended for the entire day for the

specified day(s) of the week.

• All means Storage Policies should be suspended every day of the week at the specified time.

• Use the Storage Policy Reference fields in the table to specify the Storage Policy being defined.

For example, one column might specify Oracle dbase policy, and another column might specify

Exchange policy.

•The Copies to Disk Extension Pool parameter refers to the number of physical copies of virtual

media to be created. Multiple copies of virtual media protects against physical media failures. If

multiple copies are created, each copy is created on separate physical media so the loss of one

tape does not result in total data loss. Valid values are 1 through 4 (1 is the default value).
