PreviouslyPublishedAs 213541 Description Sun StorageTek[TM] Application Storage Manager
- ASM for Solaris[TM] Steps to Follow Symptom, Cause, and Solution Symptom: After archiving has occurred to a piece of media, subsequent loading of the media results in the media being unlabeled and data lost. Cause: A problem was found with the st.conf flag settings in the example file that is provided in the software distribution. The st.conf_changes file provided in /opt/LSCsamfs/examples contains an error. NOTE: This problem only becomes a issue if the example file was used as part of the configuration process. The incorrect T9940A option flags are: The ST_AUTODEN_OVERRIDE needs to be set to prevent the Solaris ST driver from rewinding the media to BOT to determine the tape density during a Solaris ST driver recovery process. ASM is not aware that the rewind has happened so ASM writes over the label/data at BOT. Since the label/data has been destroyed, the next time the media is loaded ASM recognizes the media as unlabeled even though ASM knows that the media had been written to previously. This causes data loss at BOT. By setting this bit the problems with labels/data being overwritten is corrected. Solution: After the sampkg is installed please update the T9940A option flags in the st.conf_changes file in /opt/LSCsamfs/examples. The correct option flags should be: This file will be fixed in the next release of ASM 3.5.0 Product Sun StorageTek Application Storage Manager Sun StorageTek 9940 Tape Drive Sun StorageTek T9940 Tape Drive Internal Comments Oracle Review 1/26/10, Glen Foley CRCM, StorageTek Application Storage Manager, ASM for Solaris, T9940A Previously Published As 91034 Change History Date: 2007-10-01 User Name: 71396 Action: Approved Comment: Performed final review of article.
