All rights reserved. 18 Configuring a Shared Drive  Step 1 - Configure logical unit number (LUN) to present to the servers – One LUN will allow 15 raw partitions under the current fdisk version – One raw partition = one Oracle data file – If more than 15 data files, then more than 1 LUN is required; First Trust used six LUNs – Future releases of Red Hat Linux Advanced Server* for Intel ® Itanium ® 2 microarchitecture will increase the number of raw partitions per LUN.  Step 2 - Use fdisk to cut raw partitions – Create two 150MB raw partitions for configuration files (srvcfg and quorum) Installing Red Hat Linux Advanced Server* 2.1 on Intel ® Itanium ® 2 Microarchitecture
