LU options and settings

The MSA volumes can be created after you create a volume (RAID 0 is not supported), or they can be added later to the volume. LUNs can be configured in 16K, 32K, and 64K (default) chunks by using the advanced option. Table 2 describes the preferred options available when you create a logical unit (LU).
Table 2. Preferred options for logical units (LU)
Option Value Description
Expose to All Hosts Yes After the mapping of the volume to the Storwize V3700 completes, this is modified to All other hosts (none no access). This can be done under the Assign Host Access Privileges frame.
Automatically assign LUNs Yes This forces option expose to all hosts and is necessary for consistent LUN numbering.
write-policy write-back  
optimization any  
read-ahead-size default  
independent disable This setting controls cache mirroring. Because Storwize V3700 requires mirroring, the independent=disable option must be used.

Host options and settings for MSA2000 systems

There is no specific host option to present the MSA2000 systems to Storwize V3700 systems. Use a valid Microsoft Windows operating system as the host setting for Storwize V3700.
