For tray loss protection to work, each drive in a volume group must be in a separate
tray. If you set the
trayLossProtect
parameter to
TRUE
and you have selected
more than one drive from any one tray, the storage array returns an error. If you set
trayLossProtect
parameter to
FALSE
, the storage array performs operations,
but the volume group that you create might not have tray loss protection.
If you set the
trayLossProtect
parameter to
TRUE
, the storage array returns an
error if the controller firmware cannot find drives that will enable the new volume
group to have tray loss protection. If you set the
trayLossProtect
parameter to
FALSE
, the storage array performs the operation even if it means that the volume
group might not have tray loss protection.

whether data on a volume is accessible or inaccessible if a drawer fails. To help make

drawerLossProtect
parameter to
TRUE
.
For drawer loss protection to work, each drive in a volume group must be in separate
drawers. If you have a storage array configuration in which a volume group spans
several trays, you must make sure that the setting for drawer loss protection works
with the setting for tray loss protection. If you set the
trayLossProtect
parameter to
TRUE
, you must set the
drawerLossProtect
parameter to
TRUE
. If
you set the
trayLossProtect parameter
to
TRUE
, and you set the
drawerLossProtect parameter
to
FALSE
, the storage array returns an error
message and a storage array configuration will not be created.
