To set the data resiliency mode, type:
arraymgr -J {SingleController | Secure | Normal | HighPerformance} <array-id>
The data resiliency settings are described in
Setting
SingleController
This setting should only be used if the disk array is operating with one
controller. This suppresses the single controller warning messages that
are normally generated when the disk array is operating with one
controller. This setting will affect I/O performance. This is the default
setting for single controller mode.
Secure
Continually updates the disks with any changes in the controller maps.
This is the highest level of data protection, but it may result in
decreased I/O performance.
Normal
Updates the maps on the disks at regular intervals (typically 4 seconds).
This option offers both data protection and good performance. This is
the default setting for dual controller mode.
HighPerformance
Updates the disk maps only during shutdown of the disk array. This is
the lowest level of data protection, but it offers the highest level of
performance.
