Inquire commnad cannot show tape drives

Sorry!, Networker version in SN and server is 7.1.3

Thanks

If OS can see the drives and inquire can't I would suspect lus.conf. I'm currently at site where environment is like yours apart using Emulex 10k HBAs. I had to configure lus.conf to see drives (10k was missing there so I had to define it and add range inquire will scan). I believe that is your issue too.

If I'm right there is a big chance that in /var/adm/messages upon startup of the machine you will find message saying "no match for found in lus.conf"

Hi,

What must I configure in lus.conf????

Thanks

Probably your hba and range. Use lusbinfo to scan buses and see how your hba gets reported. Then check lus.conf for it and if it is not defined then define it as others are defined. Once that is done reload lus module.

Hi,
You are right! In /var/adm/messages there is this message:

Must I add the string to known-scsi-adapters section???
Must I reboot the machine?????

Hello,

Yes, you should add that. To be 100% sure at the bottom you can add:

name="lus" class="scsi" target=0 lun=0;
name="lus" class="scsi" target=1 lun=0;
name="lus" class="scsi" target=2 lun=0;
name="lus" class="scsi" target=3 lun=0;
name="lus" class="scsi" target=4 lun=0;
name="lus" class="scsi" target=5 lun=0;
name="lus" class="scsi" target=6 lun=0;
name="lus" class="scsi" target=7 lun=0;
name="lus" class="scsi" target=8 lun=0;
name="lus" class="scsi" target=9 lun=0;
name="lus" class="scsi" target=10 lun=0;
name="lus" class="scsi" target=11 lun=0;
name="lus" class="scsi" target=12 lun=0;
name="lus" class="scsi" target=13 lun=0;
name="lus" class="scsi" target=14 lun=0;
name="lus" class="scsi" target=15 lun=0;
name="lus" class="scsi" target=16 lun=0;
name="lus" class="scsi" target=17 lun=0;
name="lus" class="scsi" target=18 lun=0;
name="lus" class="scsi" target=19 lun=0;
name="lus" class="scsi" target=20 lun=0;

If you want you can reboot machine, but modunload (see pid with modinfo) and then modload of lux will avoid reboot option.

update_drv will do reload (modunload+modload) - not sure if you have it on Solaris 8 (I used it under 9).

Hi, again:

I have added the entry pci10df,f980:126-32C and the end of known-scsi-adapters section,but:

a) Before add this entry, inquire takes about 3-4 minutes and it can not see the tapes. The last device it can see is a disk in scsidev@5.7.0

b) After add this entry, inquire takes about 2 hours, but it can see the tapes:
scsidev@2.10.0:IBM ULTRIUM-TD2 Tape /dev/rmt/1cbn
scsidev@5.10.0: IBM ULTRIUM-TD2 Tape /dev/rmt/2cbn

Now, inquire command search for lun 0-31 in each target, and for many targets in each scsi ID (I killed the command in scsidev@5.45.31)

I think that entry pci10df,f980:126-32C is not correct but the problem is lus.conf

The ouput of lusbinfo commnad is:

Bus #2 is 'pci10df,f9800', dma_max=-1, initiator ID=255, ntargets=8, nluns=7
Bus #5 is 'pci10df,f9801', dma_max=-1, initiator ID=255, ntargets=8, nluns=7

What is the correct entry I must add in lus.conf in order to tape drives can see detected but the commnad inquire runs in a few minutes???

Thanks

You can restrict number of luns inspected with range you configure (read comments in lus.conf for more info). There is also env variable for that I believe and that information should be somewhere in docs.

I don't know on which bus is your hw so I can't tell you which one to use. From output you sent it looks like you use both so add both. Also there are few switches that might speed up the things with inquire, but they are not your issue here.

Hi,

I too have a similar issue on solaris 9 Networker server ( 7.3.3) . It has 2 LP9802 HBA's connected to 2 Fibre-SCSI bridges and they are connected to ATL P7000 SCSI Tape Library. What's happening is we have Solaris /dev/rmt/ showing all the 16 Tape drives but "inquire" is showing only 6 Tape drives on each path.

I suppose I have to update lus.cong but since we have 2 paths I wanted to know what entries should I have to add .

Thanks in advance.

Hi ,

I would like to know finally what is the resolution you found for this probelm.
Because we too have simialr problem on one of your networker server


Thanks in advance.

Add your card and range for it as described above. Use lusbinfo command to check what HBA you use (you can also check /var/adm/messages for lus messages as they would appear upon OS booting up in case that card is not part of your existing lus.conf).

Thank you so much. This solved my problem.
