Solaris 7 (Intel Platform Edition) 8/99 Release Notes

DiskSuite May Cause Data Loss (4121281)

If you are running DiskSuiteTM and upgrading to Solaris 7, you must also upgrade to DiskSuite 4.2. The DiskSuite 4.2 distribution includes a script called metacvt that automates removal and replacement of the metadb replicas. You can use that script to change the SCSI driver name stored in the replicas from cmdk to sd when you upgrade to Solaris 7 and DiskSuite 4.2.

Workaround: To avoid potential data loss during upgrades to the Solaris 7 operating environment, you must save the system's meta device configurations in text files and remove their metadb replicas before upgrading any x86 based system that is running DiskSuite. After you finish upgrading your x86 based system, you must restore the meta device configurations by using the DiskSuite command line interface.

The DiskSuite Version 4.2 Release Notes contain a procedure for saving metadb configurations, removing metadb replicas, upgrading x86 based systems to the Solaris 7 operating environment, upgrading DiskSuite to version 4.2, and restoring meta device configurations. Bourne shell scripts that automate the procedure are available for the Solaris 7 operating environment.
