5.4Checking Operation after Installation and Preparing the HDD for Use
(4)Control mode parameters
The following parameters are used to control the tagged queuing and error logging. a. Control mode parameters
| Parameter |
| Default value |
• Queue algorithm modifier |
| 0 (Execution | |
|
|
| sequence of |
|
|
| read/write |
|
|
| commands is |
|
|
| optimized.) |
• QErr: | Resume or abort remaining suspended |
| 0 (command is |
| commands after sense pending state |
| resumed) |
• DQue: | Disabling tagged command queuing |
| 0 (enabled) |
(5)Fibre channel control parameters
Refer to Subsection 4.1.4 "MODE SELECT (15)" of the Fibre Channel Interface Specifications for details.
Parameter |
| Default value |
• DTOLI (Disable Target Original Loop Initialization) |
| 0 (An Initializing LIP is issued |
|
| when the HDD enters the |
|
| Loop.) |
• DTIPE (Disable Target Initiated Port Enable) |
| 0 (The HDD does not have the |
|
| Loop Port Enable primitive, so |
|
| it enters the loop port.) |
• ALWLI (Allow Login Without Loop Initialization) |
| 0 (The HDD carries out |
|
| confirmation of the address in |
|
| the Loop Initialization |
|
| process.) |
• RHA (Require Hard Address) |
| 0 (In the Loop Initialization |
|
| process, try fixing a soft |
|
| address.) |
• DLM (Disable Loop Master) |
| 0 (The HDD itself is permitted |
|
| to become the Loop Master.) |
• DDIS (Disable DIScovery) |
| 0 (Before the INIT restarts |
|
| task processing, it must wait |
|
| for Address Discovery or |
|
| Port Discovery.) |
• PLPB (Prevent Loop Port Bypass) |
| 0 (Receiving Loop Port bypass |
|
| (LBP)/Loop Port Enable(LPE) |
|
| Primitive, it controls Port |
|
| Bypass circuit according to the |
|
| received Primitive.) |
• DTFD (Disable Target Fabric Discovery) |
| 0 (Fabric connection is |
|
| enabled.) |
Note:
It is prohibited that "1" is specified in DTIPE and PLPB simultaneously.
If DTIPE=PLPB=1 is specified, it responds with CHECK CONDITION (ILLEGAL REQUEST, VALID FIELD IN THE PARAMETER LIST.)
