• The first command activates the SSP feature. This action makes all logical drives on the controller inaccessible. • The second command specifies a logical drive and the adapter IDs or connection names that are to be allowed or denied access to the logical drive. Explicitly, these commands are as follows: modify ssp=on|off [forced] modify mask|unmask=#,#,...|all [forced] where is a controller, is a logical drive, and # represents an adapter ID or connection name. The CLI normally displays a warning prompt when you activate SSP because all logical drives are being made inaccessible.

•
The first command activates the SSP feature. This action makes all logical drives on the controller
inaccessible.
•
The second command specifies a logical drive and the adapter IDs or connection names that are to
be allowed or denied access to the logical drive.
Explicitly, these commands are as follows:
<target1> modify ssp=on|off [forced]
<target2> modify mask|unmask=#,#,...|all [forced]
where
<target1>
is a controller,
<target2>
is a logical drive, and
#
represents an adapter ID or
connection name.
The CLI normally displays a warning prompt when you activate SSP because all logical drives are being
made inaccessible. To prevent the prompt from appearing (for example, when using this command in a
batch file script), use the
forced
parameter.
Example commands:
=> ctrl ch="Lab 3" modify ssp=on forced
=> ctrl ch="Lab 4" ld 1 modify mask=210000E08B07A68F
=> ctrl ch="Lab 4" ld all modify unmask="cnxn 3","cnxn 4"
Sample scenario
First, check the SSP status of the controller:
=> ctrl ch="Lab 4" show ssp
A typical screen response could be:
MSA1000 at Lab 4
Adapter ID: 210000E08B07A68F
connectionname: Unknown
Location: Local
Status: Online
Host Mode: Default
Adapter ID: 5034414235583942
connectionname: Unknown
Location: Unknown
Status: Offline
Host Mode: Default
Now activate SSP, and then show the logical drives that are present so that you can determine which
drive to unmask:
=> ctrl ch="Lab 4" modify ssp=on forced
=> ctrl ch="Lab 4" ld all show
MSA1000 at Lab 4
array A
logicaldrive 1 (33.9 GB, RAID 0, OK)
array B
logicaldrive 2 (298 MB, RAID 1+0, OK)
logicaldrive 3 (896 MB, RAID 1+0, OK)
Finally, unmask an adapter ID and then check the SSP status:
=> ctrl ch="Lab 4" ld 1 modify unmask 210000E08B07A68F
=> ctrl ch="Lab 4" show ssp
