Solution Type Technical Instruction Sure Solution 1373231.1 : T10000/LTO/9x40 - How to Reconfigure a Tape Device After it Disappears From The Fabric
In this Document
Applies to:Sun StorageTek T10000 Tape Drive - Version: Not Applicable to Not Applicable - Release: N/A to N/ALTO Tape Drive - Version: Not Applicable to Not Applicable [Release: N/A to N/A] Oracle Solaris on SPARC (64-bit) Oracle Solaris on x86-64 (64-bit) GoalWhen a tape device disappears from the fabric, such as when a switch is disabled or a cable was pulled, the device links in /dev/rmt disappear and the device will become offline to the backup application.This document will assist in reconfiguring the tape device in the host system and re-establish communication with the Fibre Channel tape drive. Solution1. Identify the tape device or device path from the /var/adm/messages file. The device's WWN is in thedevice path. The /dev/rmt device filename mapped to this device can be identified in /etc/devlink.tab. 2. Verify that the tape device's port is enabled in the SAN switch administration tool/GUI. Make sure it is enabled. 3. Verify that the tape device is configured in the host system. # cfgadm -al Ap_Id Type Receptacle Occupant Condition c2 fc-fabric connected configured unknown c2::500104e08b3fbbe6 unknown connected unconfigured unknown c2::500104f000795ed9 tape connected configured unknown c2::500104f0009e929e med-changer connected configured unknown c2::500110a0008c35ba med-changer connected configured unusable c3 fc connected unconfigured unknown Note: the device's world wide name in the tape library configuration should match the world wide name of the device in the cfgadm output. If unconfigured, run 'cfgadm -c configure <Ap_Id>'. For example, # cfgadm -c configure <Ap_Id> If configured, verify if the symbolic link to this device exists: # ls -l | grep <pWWN> If not existing, unconfigure the device and then, reconfigure: # cfgadm -c unconfigure <Ap_Id> # cfgadm -c configure <Ap_Id> 4. Verify that the device is configured and the symbolic links are created according to the device definitions in /etc/devlink.tab # cfgadm -al # ls -l | grep <pWWN> 5. Verify if the device can be varied online in the backup application. Attachments This solution has no attachment |
