Re: How to find WWN no for SAN tape device

What do you want to do, if you know the WWN? You can use the serial number of the drive, then compare it with command view TL output.

Hope this helps!

Re: How to find WWN no for SAN tape device

I am also not sure. So what will be the main issue? Need to check physical connection between ESL-E and drives? What you suggest?

Re: How to find WWN no for SAN tape device

Hi Torsten,

 

I want to know WWN no. I have serial no which I got from hp_ltt tool.

 

The following is identity information for the selected device. You can use commands to select functionality to perform on this device.

Product ID               : Ultrium 3-SCSI
Drive Technology         : LTO
Mech. Serial Number      : HU10639DYJ
Firmware Rev             : L67W/ESL E FC
Target ID                : 5
Target LUN               : 1
OBDR Capability          : Not Supported
WORM Capability          : Supported

Cartridge Information (for cartridge currently in drive):
There is no media in this drive.

Re: How to find WWN no for SAN tape device

The most easy way would be to use command view TL.

 

With 11.23 you can only use "fcmsutil", starting with 11.31 you can do

 

# scsimgr get_info -D /dev/rtape/tape2_BEST


         STATUS INFORMATION FOR LUN : /dev/rtape/tape2_BEST
 
Generic Status Information
 
SCSI services internal state                  = UNOPEN
Device type                                   = Sequential_Access
EVPD page 0x83 description code               = 1
EVPD page 0x83 description association        = 0
EVPD page 0x83 description type               = 3
World Wide Identifier (WWID)                  = 0x50060b000059f20a
Serial number                                 = HU10617K90
Vendor id                                     = HP       
Product id                                    = Ultrium 3-SCSI

...


Hope this helps!
Regards
Torsten.

Re: How to find WWN no for SAN tape device

"Actually SAN team asking tape WWN no for zoning."

 

Is the tape drive already zoned with your server?

 

If so, the SAN team should be able to find the WWN either in the SAN-switch or in the Library's Command View TL.

If not, then you cannot find the WWN of the tape drive on the server.

Re: How to find WWN no for SAN tape device

scsimgr is working perfectly with HP-UX 11.31. But in my case OS version is HP-UX 11.23. I am unable to find exact command syntax to use with fcmsutil to get WWN details for tape device.
