If an identifier for a SCSI object is specified, attributes specified can be generic, class
driver specific or interface driver specific attributes maintained for the SCSI object. So
there is no need to specify option "
-d driver" to save driver specific attribute for SCSI
objects.
However, to save a class or interface driver’s global specific attributes you must specify
the "
-d driver" option. If you specify the option "
-d driver", you can only specify this
driver specific attributes, otherwise, the command will fail for all non driver specific
attributes.
Usage:
scsimgr save_attr [identifier] default
[ -a attr ... -a attr ]
scsimgr save_attr [-d driver][identifier]
-a attr ={value|default}...
-a attr ={value|default
}
Note:
• identifier identifies either a LUN, LUN path, target path, target port, a SCSI HBA con-
troller or a settable attribute scope for a driver.
• To differentiate the string
default from the keyword default, you must assign the
string as:
attr
=’default’
WARNINGS: Changing attribute values at a registered scope for a driver (for example,
device type, vendor identifier, or product identifier) may affect interoperability with cer-
tain devices or proper operation of the system. It should be done only by experienced
users. HP recommends that you consult your HP support representative before changing
attribute values.
set_attr Set current values of global attributes or attributes of a single SCSI object. Values set in
this manner remain so only until the system is rebooted (non persistent). To save this
value across reboots (persistent), use the
save_attr command.
Only values of attributes that are settable or read-write values can be set. To view the
settable values, use
get_attr with the keyword settable. In case of the value being
set is a string including a space, it should be specified within double quotes ("...").
If no identifier or keyword for a group of SCSI objects is specified, attributes specified
should be global generic attributes.
If an identifier for a SCSI object is specified, attributes specified can be generic, class

set_devid See get_devid above.
sync_cache Requests synchronization of the write cache of a block device. Data in the cache are writ-
ten in the medium.
