To remove a RAID, if previously added to Volume Group, please enter the console Extended tools
(press F1 on console to find out keyboard shortcuts) and first delete Volume Group of the RAID (

content of units
function in Extended tools menu). When this is finished, the ‘Remove’ button will be
enabled. Otherwise simply press ‘Remove’ button.
Note: You can add spare units to RAID1, RAID5 and RAID6 arrays. Please remember that
after creation of an RAID, in Function: 'Info' will be shown progress of Synchronization. Until
this process is finished, all actions on this array will be slower.
Note: If Units are connected through Fibre Channel with only one LUN, then its not recommended to
create s/w RAIDs on these Units, because this would slow down the system. If Units come from two
different LUNS connected by way of two different paths, then you can create s/w RAIDs with no
problem.
Function: S/W RAID e-mail notification fig 3.1.5b
It is possible to send notification by e-mail about events on software RAID arrays (e.g. rebuild started,
rebuild finished, span is active). In order to do so please check Send array events.
In order to Send array events you must enable “E-mail notification” in “setup”
“administrator”.
