Re: Mapping an Emulated DASD device to an SVC LUN number

[Romanowski, John (OFT)]

The SVC command line command
 svcinfo lshostvdiskmap
might list the information you're looking for. Look online for the manual

"IBM TotalStorage SAN Volume ControllerCommand-Line Interface User’s Gu
ide"

Here's sample output (probably folded across two lines); the SCSI_id colu
mn
is the  LUN's hex id in decimal (decimal 102 below is hex LUN id 0066)
svcinfo lshostvdiskmap Z10_P1-T1Linux
id               name              SCSI_id        vdisk_id       vdisk_na
me
       wwpn             vdisk_UID
240              Z10_P1-T1Linux    102            186       
    
Z_TZ2BF152_V2     5005076401E2893A 6005076801818076280000000000062F
240              Z10_P1-T1Linux    103            667       
    
Z_TZ2BF152_V3     5005076401E2893A 60050768018180762800000000000633

(the SVC's SCSI_id column is not to be confused with the value given by
linux's scsi_id command. I found that prefixing 3 to the SVC's vdisk_UID 
is
the same value returned by linux's scsi_id command)
