Information in this document applies to any platform.


After the release of the original Oracle Database Appliance (ODA)v1, the newer hardware versions have the option of an additional second Storage Disk Array. For the X4-2 and X3-2 the second shelf are identical (DE 24p) doubling the storage capacity. For the X5-2 a unique shelf is added which includes a different configuration and size of disks ( not swappable with X3-2 or X4-2 storage). This Second JBOD (Just a Bunch Of Disks) automatically configures ASM storage. Under most circumstance this second JBOD can be added without user intervention other than cabling and powering up the unit. For various reasons JBOD addition is not always successful. . This Note has four parts. 1) Proactive - Best Practice before adding a JBOD.  2) Reactive which will discuss some of the situations that may be encountered adding a second JBOD. For example, due to natural occurring updates newer JBOD disks and firmware may result in a gap between older ODA configuration and newer manufactured JBODs

Does not apply to X6-2*, X7-2* or newer hardware versions.
