HP MSL TAPE DRIVE NOT DETECTING IN REHL4

HP MSL TAPE DRIVE NOT DETECTING IN REHL4

We have HP MSL6060 tape library with two NSR card each connected to one and other SAN Switch port. MSL is having two drives. Each san switch fibre cable goes to Linux REHL4 host. Similary it is connected to Open VMS host.
One Tape drive and NSR was faulty and replaced. WWN no of linux and OVMS hosr are configured in NSR also alias for NSR is configured in SAN Swich. We have made reboot of linux host but replced drive is not detecting. Other working drive has no issue.

In OVMS host both drives are working fine.

Qlogic HBA utility run on Linux host but do not shoe replaced Tape drive. How to configure in Linux host or detect. Any file modification required. Please provide solution. Attched utility output.

Double check your replaced NSR and its zone in the SAN switch sir.

Two Linux host wwwn is mapped as indexed in NSR. It is seen in NSR report. Also NSR wwn no is configured in alias of SAN switch also active in backup zone. Out of two MSL drive one drive which is working is accessible through both linux host. Only Replaced drive is not accessible.

Have you tried rebooting your NSRs since the drive was replaced? Then performing a scsi scan on your Linux host afterwards?

Tape library was power cycled then after Linux REHL4 host reboot taken. Then observed same problem.

Re: HP MSL TAPE DRIVE NOT DETECTING IN REHL4

But are teh NSR cards "reset" too when the Library is restarted?

Is there not a reset on the NSR itself?

Man -- in the old days NSRs are separate devices.

Re: HP MSL TAPE DRIVE NOT DETECTING IN REHL4

Here the TAPE library is HP MSL6060. When we power recycle it resets all devices.

Same issue of non detection of one drive was also on Open VMS 8.3 systems. on restarted also problem did not resolved. we have to find new wwid of NSR by command mc sysman> find wwid which has modifided sys$sysdevice.dat file addding new enrty of NSR. I suspect some issue detctin on LInux REHL host. Any command to detect on REHL4 or hardware specific issue.

Then I guess check with your FIretils -- SAN surfer or whatevr EMulex tool (depends on your FC-HBA) you may have.
