(Doc ID 1001972.1)

Last updated on OCTOBER 17, 2017

Applies to:

Solstice DiskSuite Software - Version 2.0.1 to 4.2.1 [Release 2.0 to 4.0]
Sun Solaris Volume Manager (SVM) - Version 11.9.0 to 11.11 [Release 11.0]
Oracle Solaris on SPARC (32-bit)
Oracle Solaris on x86-64 (64-bit)
Oracle Solaris on x86 (32-bit)
Oracle Solaris on SPARC (64-bit)

Goal

For whatever reason, circumstances necessitate the need to recover an existing Solaris Volume Manager (SVM) diskset.
Sometimes a diskset configuration can be so corrupted that the only way to recover it is to delete the diskset and recreate it.

When a diskset is deleted, only the configuration information is gone, but the underlying data in the disks are still intact. As long as the original disks belonging to the diskset are still available and have not been used for something else, the diskset can be recreated and the data from the metadevices can be recovered.

The only requirements are previously saved output from:

If there was a previously saved Sun Explorer from the system, then output of these commands can be found in <explorer>/disks/sds or <explorer>/disks/svm .
