+## Prepare and format flash memory
+
+After you [install Redis Enterprise Software](#install-redis-enterprise-software), use the `prepare_flash` script to prepare and format flash memory:
+
+```sh
+sudo /opt/redislabs/sbin/prepare_flash.sh
+```
+
+This script finds unformatted disks and mounts them as RAID partitions in `/var/opt/redislabs/flash`.
+
+To verify the disk configuration, run:
+
+```sh
+sudo lsblk
+```
