scsimgr issue

[Bala C]

Hi Folks,

Two HP Ultrium - 3 tape drives were replaced in the library.
I have two 11.31 servers where the tape drives are zoned, I faced issue in one server using the scsimgr replace_wwid -D dsf whereas the other this command fixed and detected the new tape device.

All the 11.23 servers which were zoned, I was able to fix using fcmsutil replace_disk.

64000/0xfa00/0x18
0/0/6/1/1.0x500e09e00aef7310.0x0 0/0/6/1/1.1.19.255.0.0.0

# scsimgr -f replace_wwid -H 64000/0xfa00/0x18
scsimgr: Successfully validated binding of LUN paths with new LUN.

# ioscan -fnC tape |grep stape
tape 11 0/0/6/1/1.1.19.255.0.0.0 stape NO_HW DEVICE HP Ultrium 3-SCSI

As you see the above output, the scsimgr replace_wwid command hasn't fixed the issue.

I also ran scsmgr replace_leg_dsf


# scsimgr replace_leg_dsf -D /dev/rtape/tape6_BEST
Do you really want to replace? (y/[n])? y
scsimgr: Legacy device file '/dev/rmt/c31t0d0BEST' binding to LUN changed successfully

# ioscan -fnC tape |grep stape
tape 11 0/0/6/1/1.1.19.255.0.0.0 stape NO_HW DEVICE HP Ultrium 3-SCSI


Is there any other option? Or Am I doing a mistake somewhere?

Kindly help.

Or Reboot the only option?

Thanks.

Usually you will find guidance in "dmesg" or syslog.log on what to do with scsimgr to fix your issue with replaced LUNs - disk or tape. Have you followed that?

If not -- I guess go to the reboot option if you can afford the downtime.

Ofsourse, I completely followed the scsimgr replace_wwid procedure.I t worked on other other 11.31 server but not on this one.
