All,

Solution:
hwmgr delete -did 10
There was a further problem when I tried to move tape1 to tape0, gave
message;
MARS:root> dsfmgr -m tape1 tape0
dsfmgr: ERROR: second device status is active: tape0
dsfmgr: ERROR: move failed: Device is in use
secondary solution:
MARS:root> grep tape 0 /etc/dfsc.dat
grep: can't open 0

from Chris Eckert follows;
Try deleting that device using the device id.
hwmgr delete -did 10
#hwmgr show comp (To get the tape0 hardware id)
#hwmgr -delete comp -id 25 (Remove the tape0)
Now the dsfmgr -m command should work.
from Roberto Romani follows;
hwmgr -delete scsi -did DID (device ID)
with secondary communication of (for further problem);
grep tape 0 /etc/dfsc.dat <- note the spaces between tape 0 a they have to
be there.
/etc/dfsc.dat:I: tape 4
/etc/dfsc.dat:A: 0 1300073 61 14 18 c ""
/dev/ntape/ tape 0 ""
/etc/dfsc.dat:A: 0 1300077 61 14 8 c ""
/dev/ntape/ tape 0 _d0
/etc/dfsc.dat:A: 0 1300079 61 14 9 c ""
/dev/ntape/ tape 0 _d1
/etc/dfsc.dat:A: 0 130007b 61 14 10 c ""

/etc/dfsc.dat:A: 0 130007f 61 14 12 c ""
/dev/ntape/ tape 0 _d4
/etc/dfsc.dat:A: 0 1300081 61 14 13 c ""
/dev/ntape/ tape 0 _d5
/etc/dfsc.dat:A: 0 1300083 61 14 14 c ""
/dev/ntape/ tape 0 _d6
/etc/dfsc.dat:A: 0 1300085 61 14 15 c ""
/dev/ntape/ tape 0 _d7
/etc/dfsc.dat:A: 0 1300075 61 14 19 c ""
/dev/ntape/ tape 0 c
in this case the HWID for tape 0 is 61
so
dsfmgr -R hwid 61
this should remove the entries for tape0 then you can remap tape1 to tape0
from Michael Polnick follows;
It's not possible to delete a HWID=0. Just use the
SCSI device id:
hwmgr -delete comp -did 10
from Dave Burden follows;
Try using these two commands:
# hwmgr -del comp -id 0
# hwmgr -del scsi -did 10
I've found the first one usually works best, but you may have to do it
twice
to have it work.
from Shawn Cromer follows;
To make the tape and CD-ROM change from null to actual devices do the
following:
# /sbin/dn_setup -install_tape
Then show devices again
# hwmgr -v d
This will correct the tape drives. Have not seen the CD-ROM as null. But
give it a try.

Subject: hwmgr delete - HWMGR_REQ buffer contains bad parameters
Hi All,
ES40, HSG80
TRU64 V5.1A, patch kit 4. (T64V51AB21AS0004-20030206 OSF520)
I am trying to delete a device which does not exist on our system, but get
error;
hwmgr: HWMGR_REQ buffer contains bad parameters or sizes are invalid.
We have 2 ES40 which are connected to HSG80. Only one ES40 is booted at a
time, the other is on standby (redundancy). Periodically we down the live
ES40, at the HSG we disconnect and associate the disks to the alternate
ES40 and boot this. Hence we get null devices for tape and cdrom, and I
normally just delete these, then use dsfmgr to reassign to normal device
file. But this one wont go.... all suggestions welcome.
Here are the commands I've used;
MARS:root> hwmgr -show scsi
SCSI DEVICE DEVICE DRIVER NUM DEVICE FIRST
HWID: DEVICEID HOSTNAME TYPE SUBTYPE OWNER PATH FILE VALID PATH
-------------------------------------------------------------------------
0: 10 MARS tape none 0 1 (null)
48: 1 MARS disk none 2 5 dsk0 [4/3/11]
49: 2 MARS disk none 2 5 dsk1 [4/3/12]
54: 0 MARS raid none 0 5 scp0 [4/3/0]
55: 3 MARS raid none 0 5 scp1 [4/1/0]
68: 7 MARS cdrom none 0 1 cdrom0 [2/0/0]
69: 6 MARS tape none 0 1 tape1 [1/6/0]
MARS:root> hwmgr delete -id 0
hwmgr: HWMGR_REQ buffer contains bad parameters or sizes are invalid.
MARS:root> hwmgr -show scsi -full -id 0
SCSI DEVICE DEVICE DRIVER NUM DEVICE FIRST
HWID: DEVICEID HOSTNAME TYPE SUBTYPE OWNER PATH FILE VALID PATH
-------------------------------------------------------------------------
0: 10 MARS tape none 0 1 (null)
WWID:03100032:" SONY SDX-300C **********"

Thanks
