Because the hardware and device paths will change, the library save/restore features can not be used to re-enter old settings. Upgrade library and drive firmware. a. Upgrade the firmware for all library components so they will recognize the LTO4 or later tape drive. b. Upgrade the drive firmware for all LTO2 and LTO3 tape drives in the library so they will properly handle the LTO4 or later tape drive media. IMPORTANT: LTO2 and LTO3 tape drives require the most recent firmware to immediately identify LTO4 and later media. Without the most recent firmware, loading an LTO4 or later cartridge into an earlier generation drive may result in a long media identification and unload time. The drive may not identify the media and return a load error before the application times out waiting for the load. HP strongly recommends keeping your tape drives updated to the most recent firmware. 3. 6.

Connect the end of the Ethernet cable that you disconnected from the old tape drive to the MGMT port on the new tape drive. b. Verify that the other end of the Ethernet cable is connected to the internal network switch installed in the library. 8. Install the new tape drive. Page 11 13. Ensure that the tape drive has the latest firmware for correct operation. If necessary, upgrade the drive firmware using the Command View TL firmware upgrade wizard or the Interface Manager card CLI. See the HP Interface Manager and Command View TL User Guide for detailed procedures on upgrading drive firmware. NOTE: If the Interface Manager is running 2.61 or older firmware, connect to the Interface Manager card CLI using telnet, once logged into the CLI use the sync sec command to force the mapping changes into the new drive. NOTE: After a drive replacement or firmware upgrade, you may be required to run specific OS commands from the HPUX host in order to verify the drive path. See “Ensure the new drive is CLAIMED and online” (page 12). IMPORTANT: Do not connect the MGMT port or internal network switch to the public or site LAN. 11. Verify that the FC port A LED on the new tape drive is green when connected to a switch and linked. Ensure the new drive is CLAIMED and online In an HPUX 11.31 (or newer) environment, there is a new SCSI software behavior which identifies a device through its World Wide Identification (WWID). When drive firmware is changed, or the drive is replaced, it is possible that the WWID information is also changed. This will cause HPUX SCSI stack to stop all IO communication to the device. In this case, an ioscan shows the device in a NO_HW state, and the new WWID must be validated on the HPUX host side to allow SCSI IO communication. If this situation occurs or is suspected, view the file /var/adm/syslog/ syslog.log and look for the message similar to this example: Evpd inquiry page 83h/80h failed or the current page 83h/80h data do not match the previous known page 83h/80h data on LUN id 0x0 probed beneath the target path (class = tgtpath, instance = 3). The lun path is (class = lunpath, instance = 0). Run 'scsimgr replace_wwid' command to validate the change. 12. Close the back doors of the library. If this message appears, perform the following procedure for HPUX host commands. Page 12 1. 2. 3. 4. 5. 6. 7. Verify that HPUX 11.31 patch ID PHKL_41474 is installed. Login (at root level) to the HPUX server. Run ioscan –fnN, ioscan –fnC tape, and ioscan –m lun to establish the drive path before the change was done, place the drive online, and determine the device file needed for the replace_wwid command used later in this procedure. From CVTL or the Interface Manager CLI, execute the firmware update of the appropriate drive. From the HPUX host run ioscan. (Do not run any other version of ioscan.) Compare these to the syslog error message and identify the proper tape device name through the lunpath/tgtpath. From the HPUX host run scsimgr –f replace_wwid –D /dev/rtape/tape[##]_BEST dsf, where [##] is the device file for one of the tape drives, to validate the new WWID on the previous hardware path. From the HPUX host run ioscan –fnC tape to verify that the devices are claimed and accessible. After an EML LTO5 drive is upgraded from I25S firmware to something newer, perform the above procedure to get the drive CLAIMED and online.
