End Keyword
End
is a required keyword, indicating the end of the block.
HotspareDrives Keyword
HotspareDrives
is an optional keyword, specifying the hot spares to
assign to the array. The syntax for listing hot spares is the same as the
. If
HotspareDrives
is not specified, no hot
spares are assigned to the array.
For example:
HotspareDrives=0:0:0,0:1:0
The same disk drive can be assigned to protect multiple arrays (as a
pool spare). Once a pool spare is used by a failed disk drive, however, it
is no longer available to protect the other arrays its assigned to.
This keyword does not verify that the available space on the specified
hot spares is sufficient to serve as failover for the array.
When assigning hot spares to a multilevel array,
HotspareDrives
assigns
all the hot spares in the list to all arrays within the multilevel array.
InitializeAll Keyword
If you want the ACU to initialize all drives connected to the controller
and delete any existing arrays before any new arrays are created, even
those that are not specified in any
Drives
keyword definition, specify
InitializeAll=yes
. Otherwise, the ACU initializes only those drives
specified by the
Drives
keyword.
Caution:
Initializing a disk drive automatically deletes any existing
arrays with that disk drive as their member.
Possible values:
●
Yes
—Initialize all drives.
●
No
(default)—Do not initialize all drives; only those drives specified
with the
Drives
keyword are initialized.
For example:
Type=Volume
Type=RAID1
!
