In case one of our customer had drive replacement it’s mean that serial number also change. So in order to update the serial number in SSO environment. Here’s the steps.
1. tpautoconf -report_disc , this command will list what device that had been missing or found.
2. tpautoconf -replace_drive drive_name –path drive_path, this command will update the existing device configuration with the new one.

#cd /usr/openv/volmgr/bin
#tpautoconf -report_disc

Our SL8500 has LSM 0-3, 1st 3 are for UNIX and LSM3 is for MVS. If we replace drives on MVS, what updates are necessary. HSC was defined with the internal address and ACSLS index, not S/N ?
I don’t hv any experince with MVS that connect to SL8500. But I had replaced drive Timberline 9490 and T9940B on STK Powderhorn 9310+MVS/HSC; i just write down the configuration from old drive, LIB ADDRESS and DRIVE ADDRESS then Apply it on new drive, thats all. i don’t know if u use LTO drive, as far as i know there is no internal configuration on LTO drive.
What i talked above just to change serial number, although we set “Dynamic WWN” on SL8500 and no need to reconfigure again but the serial number still same as old drive.
very interesting, but I don’t agree with you
