initiaLization
Technically speaking, Initialization is a foreground activity, as you cannot access a logical drive while it is
initiating.
Initialization is normally done to logical drives after they are created from a disk array. Initialization sets all data
bits in the logical drive to zero. The action is useful because there may be residual data on the logical drives left
behind from earlier congurations. For this reason, Initialization is recommended whenever you create a logical
drive.
Initialization of an LD will pause any other Background Activities that are running. To initialize an LD or
multiple LDs on a VTrak node:
1. Go to SAN > Background Activities menu tab
2. Choose the VTrak node that has the LD or LDs to initialize in the left panel.
3. Click on the Play icon (blue triangle inside blue circle) to bring up the Initialization settings menu.
4. The menu lists all the LDs on the node. Choose the Initialization options for any or all LDs, and click the
Save button to save the settings start initialization. Options include Quick Initialization . To select all LDs
for initialization, click to check mark the Logical Drive option box.
A progress bar will display under Current Running Background Activity showing how much of the
initialization is completed on each LD. Click the Gear icon to display the Stop, Pause and Resume
options to stop, pause or resume initialization of an LD.
Note
LD Initialization Rate is Medium by default. This setting is chosen to
balance system resources between initialization and ongoing read/
write operations on other LDs. Use the Background Activities Settings
menu to change this rate.
