Legato 3000 NetWorker Storage Node for MPE/iX

by Alex Early Commercial Systems Division

The HP 3000 NetWorker Storage Node for MPE/iX is supported in MPE/iX 6.0 Express 1. The HP 3000 NetWorker Storage Node for MPE/iX allows the HP 3000 to support directly connected DLT7000 libraries. The Storage Node requires additional Legato software, NetWorker server software (NT or UNIX), and Autochanger license. With the Storage Node, the HP 3000 supports DLT 1/8, 2/15, 2/28, 3/30, 4/48, etc... A complete list can be found at http://www.hp.com/go/3000.

Configuring Libraries on MPE/iX

To configure the DLT Library on an HP 3000, perform the following steps:

After booting, run ODE at the ISL prompt:
```
ISL> ODE
```
NOTE: The MPE ISL ODE "RUN MAPPER" utility does not recognize and list fast-wide robotics devices.

Run mapper to get device paths:

ODE> RUN MAPPER
***STARTING EXECUTION OF MAPPER****
Processor Identification:
...I/O Configuration:
Type HW SW Revisions
Path Component Name ID Mod Mod Hdwr Firm 
...
/4/4 HP-PB Fast Wide SCSI . . .
/4/4.0.0 C1194F . . .
/4/4.1.0 DLT7000 . . .
/4/4.2.0 DLT7000 . . .
/4/4.3.0 DLT7000 . . .
/4/4.4.0 DLT7000 . . .

Boot the system. At the MPE prompt, run sysgen and start the io section:

: sysgen
SYSGEN version E . . .
sysgen> io
** IO configurator commands **

If not already configured, configure the differential card and the pseudo/target level of the SCSI path:

io> apath 10/4/4 id=HP28696A
io> apath 10/4/4.0 id=pseudo
io> apath 10/4/4.1 id=pseudo
io> apath 10/4/4.2 id=pseudo
io> apath 10/4/4.3 id=pseudo
io> apath 10/4/4.4 id=pseudo

Configure the robotic transport/"picker" and DLT tape drives:

io> adev 30 id=HPC1194F path=10/4/4.0.0
io> adev 31 id=DLT7000 path=10/4/4.1.0 mode=autoreply 
io> adev 32 id=DLT7000 path=10/4/4.2.0 mode=autoreply 
io> adev 33 id=DLT7000 path=10/4/4.3.0 mode=autoreply 
io> adev 34 id=DLT7000 path=10/4/4.4.0 mode=autoreply

Verify the bindings between the PATH, LDEV number, ID, PMGR (device drivers), and LMGR attributes for each device configured.
- Verify the binding for the device adapter (the fw/differential dam):
```
io> lpath 10/4/4.0.0
PATH: 10/4/4 LDEV:
ID: HP28696A TYPE: DA
PMGR: FWSCSI_DAM PMGRPRI: 6
LMGR: MAXIOS: 0
```
  Repeat this verification step for lpath 10/4/4.1, 4.2, 4.3, and 4.4.
- Verify the binding for the targets (the transparent dm):
```
io> lpath 10/4/4.0
PATH: 10/4/4.0 LDEV:
ID: PSEUDO TYPE: DA
PMGR: TRANSPARENT_MGR PMGRPRI: 6
LMGR: MAXIOS: 0
```
  Repeat this verification step for lpath 10/4/4.1, 4.2, 4.3, and 4.4.
- Verify the binding for the picker (the pass-through driver):
```
io> lpath 10/4/4.0.0
PATH: 10/4/4.0.0 LDEV: 30
ID: HPC1194F TYPE: MOSAR_AC
PMGR: MO_SCSI_PTHRU_DM PMGRPRI: 10
LMGR: LOGICAL_DEVICE_MANAGER MAXIOS: 0
```
  Repeat this verification step for lpath 10/4/4.1, 4.2, 4.3, and 4.4.
- Verify the binding for the tape drives (the differential tape dm):
```
io> lpath 10/4/4.1.0
PATH: 10/4/4.1.0 LDEV: 31
ID: DLT7000 TYPE: TAPE
PMGR: SCSI_TAPE2_DM PMGRPRI: 10
LMGR: LOGICAL_DEVICE_MANAGER MAXIOS: 0
```
  Repeat this verification step for lpath 10/4/4.2.0, 4.3.0, and 4.4.0.

Configuring the Storage Node on the NetWorker Server

Complete the configuration process on the Storage Node on the NetWorker server.

Verify the ldev Specifications

io> ldev 30/34
LDEV: 30 DEVNAME: OUTDEV: 0 MODE:
ID: HPC1194F RSIZE: 128 DEVTYPE: MOSAR_AC 
PATH: 10/4/4.0.0 MPETYPE: 24 MPESUBTYPE: 4 
CLASS:
LDEV: 31 DEVNAME: OUTDEV: 0 MODE:
ID: DLT7000 RSIZE: 128 DEVTYPE: TAPE
PATH: 10/4/4.1.0 MPETYPE: 24 MPESUBTYPE: 8 
CLASS: TAPE
...
LDEV: 34 DEVNAME: OUTDEV: 0 MODE:
ID: DLT7000 RSIZE: 128 DEVTYPE: TAPE
PATH: 10/4/4.4.0 MPETYPE: 24 MPESUBTYPE: 8 
CLASS: TAPE

Save the Configuration Changes

Hold the configuration changes:
io> hold
Exit the io section:
io> exit
If you have followed the local convention for backing up the configuration file, keep the changes:
sysgen> keep keeping to group CONFIG.SYS
Purge old configuration (yes/no)?y
IMPORTANT: Check with system management to make sure you can keep the changes to the configuration file.
Exit sysgen and reboot according to local convention:
sysgen> exit
