missing drive path

Hi Friends,

 

 

I need your help in solving below mentioned path issue with drive

 

# tpconfig -d

Id  DriveName           Type   Residence

      Drive Path                                                       Status

****************************************************************************

0   HP.ULTRIUM4-SCSI.000 hcart  TLD(0)  DRIVE=1

      /dev/rmt/7cbn                                                    DOWN

1   HP.ULTRIUM4-SCSI.001 hcart  TLD(0)  DRIVE=2

      /dev/rmt/4cbn                                                    DOWN

      /dev/rmt/6cbn      

 

 

one path /dev/rmt/0cbn is missing for drive 0

I can access all the paths with mt command as below

 

 

# mt -f /dev/rmt/4cbn stat

/dev/rmt/4cbn: no tape loaded or drive offline

# mt -f /dev/rmt/6cbn stat

/dev/rmt/6cbn: no tape loaded or drive offline

# mt -f /dev/rmt/7cbn stat

/dev/rmt/7cbn: no tape loaded or drive offline

# mt -f /dev/rmt/0cbn stat

/dev/rmt/0cbn: no tape loaded or drive offline

#

 

 

I tried to remove the drive 0 and then ran tpautoconf -a

 

 

# tpautoconf -a

Currently defined robotics are:

  TLD(0)     robotic path = /dev/sg/c0tw5001438016056cabl1

 

 

 

There is no improvement after readding the drive in netbackup

 

Below is the output of scan command

Try deleting the tape devices from /dev/ as Marianne and myself have recommended and get the OS to rediscover them.

Then provide output of :

ls -l /dev/?cbn

scan -tape

removing the drive and re-running tpautoconf will not work if scan does not see the device, which it does not in this case.

Have you tried deleting the drives, deleting the /dev/?cbn devices and rediscovering them with a reboot to see if they all come back?

Also check the NetBackup Device Configuation Guide

It seems there are more /dev/rmt entries than actual tape drives - even if there are 2 paths per tape drive. This is normally an indication that there is no Persistent Binding in place between hba and OS. This will cause new device names getting created during reboot. So, 1st step is to cleanup /dev/rmt. Simply delete all entries in the folder. Recreate with devfsadm. Next, use hba tools to config Persistent Binding. Check that devices respond to scsi_commands with scan and sgscan. Rebuild sg driver if sgscan does not pick up all drives (search this forum for sg.build and sg.install ). Delete all devices in NBU and run device config wizard to re-add.

mt command is rocognising all the 4  paths even the 0cbn i.e missing as shown in prevoius comment.

that means drives are accessible from OS .

and there are only paths related to 4 drives as shown below in /dev/rmt

Try deleting the tape devices from /dev/ as Marianne and myself have recommended and get the OS to rediscover them.

Then provide output of :

ls -l /dev/?cbn

scan -tape

Have you tried to rebuild sg driver as recommended in my previous post?

See this forum post:

recreate /dev/sg/* on solaris 10 without reboot

Hi Marianne,

Sorry for bypassing the post. I am even facing the same issue.

I have one robot and two drives. But it shows twice. I believe there is no persistant binding between OS and HBA.

I have NB on linux redhat ES 4. After every reboot the paths are missing and creating prob when taking backups. reconfiguring stu manually always is not right solution I think

Can you please let me the steps to follow the persistant binding, 

Awating for the reply

 

Cheers
