SCSI Device Conﬁguration Examples for N-Class and A-Class HP e3000 Systems

LDEV: 7 DEVNAME: OUTDEV: 0 MODE:

ID: HPC1553A RSIZE: 128 DEVTYPE: TAPE

PATH: 0/0/1/0.6.0 MPETYPE: 24 MPESUBTYPE: 7

CLASS: TAPE TAPE2 DDUMP TAPE1

This covers the basics of conﬁguring a single Disk and single Tape; now, on to the special

cases.

The MPE/iX Operating System requires several logical devices to be present in order to

function properly. LDEV 1, LDEV 7 and LDEV 20 are the basic hardware devices that

must be present. In addition MPE/iX requires that LDEV 10 be conﬁgured as the

“Streams” device and that a spooled printer be conﬁgured, usually LDEV 6 with Class LP

or PP, in order for Jobs to Logon. Neither of these devices has to be physically present but

they must be conﬁgured. If your system has been factory preloaded, these devices should

already be present in conﬁguration ﬁles found in the group CONFIG.SYS. Alternately,

they should be found in the groups CONFNCL1, CONFNCL2 (N-Class), CONFACL1, and

CONFACL2 (A-Class).

In order to conﬁgure these “virtual” LDEVs you must use a real hardware path up to the

Device Adapter, but you do NOT have to have actual LDEV6 and LDEV10 devices

physically present. We recommend that these devices be conﬁgured with the special Target

Ids 16 (sixteen) and 17 (seventeen) so as to not artiﬁcially limit the number of devices

allowed on a SCSI Bus (the PCI_SCSI_DAM software will allow these normally illegal

values for “virtual” LDEVs). New Device IDs have been added to IODFAULT.PUB.SYS to

ensure proper conﬁguration of these special devices:

LP_PP_ID: use for the System Printer

JOBTAPE_ID: use for the Streams device

Assuming that LDEV 7 was previously conﬁgured at path 0/0/1/0.2.0 as in the previous

examples the actual SYSGEN commands to add LDEV 6 and LDEV 10 would be:

io> ap 0/0/1/0.16 id=pseudo

io> ad 6 path=0/0/1/0.16.0 id=lp_pp_id

or (if ldev 6 already defined but not valid or being used)

io> md 6 path=0/0/1/0.16.0 id=lp_pp_id

The streams device (LDEV10) must have OUTDEV parameter set to an existing spooled device class.

In this case LP-PP-ID has a default class of PP, so that is the value we use for OUTDEV

io> ap 0/0/1/0.17 id=pseudo

io> ad 10 path=0/0/1/0.17.0 id=jobtape_id outdev=pp

or (if ldev 10 already defined but not valid or being used)

io> md 10 path=0/0/1/0.17.0 id=jobtape_id outdev=pp

From the CONFNCL1 ﬁle:

LDEV: 6 DEVNAME: OUTDEV: 0 MODE:

ID: LP_PP_ID RSIZE: 66 DEVTYPE: PP

PATH: 0/0/1/0.16.0 MPETYPE: 32 MPESUBTYPE: 6
