Notes:
• Setting the value of attribute max_q_depth for a LUN, will set the queue depth for all LUN paths of
the LUN to the value specified.
• The queue depth of LUN paths of a LUN can also be changed as follows:
scsictl -m queue_depth
However scsictl -m queue_depth only affects the current value while scsimgr can set the
value persistently across system reboots.
• If scsictl is invoked on a persistent DSF, it only affects the current value of all LUN paths. If it is
invoked on a legacy DSF, it only affects the current value of the queue depth on the LUN path
corresponding to the legacy DSF.
• If the current value is changed with the ssictl command while the LUN is not opened, this value will
be lost when the LUN is opened. The value saved or set at a higher scope with the
scsimgr command
will be restored.
• If the value of the escsi_maxphys global attribute is changed, the new value is used for the computation
of the actual maximum I/O size of a given LUN only when one or more of these situations occurs:
• The LUN is opened the first time.
• A new lunpath is registered for the LUN.
• An existing lunpath for the LUN is deleted.
The actual maximum I/O size for a LUN is determined by whichever is the smallest of these two values:
• the escsi_maxphys attribute or
• the maximum I/O sizes reported by interface drivers on lunpaths of the LUN.
RETURN VALUE
scsimgr exits with one of the following values:
0 Operation successful.
