scsimgr(1M) scsimgr(1M)
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 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, a SCSI HBA controller 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’
• WARNING: Changing attribute values at a registered scope for a driver (e.g.
device type, vendor identifier, product identifier, etc.) should be done with
extreme care. We recommend you consult your HP support representative
before doing so.
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 sett-
able 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 ("...").

able attribute scope for a driver.

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.
