What The Heck is RAID 10?

Solstice DiskSuite / Solaris Volume Manager Soft Partitioning


Solaris Volume Manager provides storage management tools that enable you to create and manage RAID 0, RAID 1, and RAID 5 volumes, as well as transactional (logging) devices and soft partitions. Solaris Volume Manager provides all of the capabilities of Solstice DiskSuiteTM and adds the following:

  • Soft partitions - Allow numerous partitions on a single drive, thus breaking the 8-slice barrier
  • Device ID support - Preserves Solaris Volume Manager configuration even if disks are moved or rearranged
  • Active monitoring of disks - Detects silent failures
  • Solaris Management Console based interface - Enables you to manage the enhanced storage devices through the same management interface that is used for other Solaris management tasks
  • Solaris Volume Manager WBEM application programming interface (API) - Enables standards-based management of Solaris Volume Manager from any compliant tool
  • The Solaris 9 release seamlessly supports upgrading existing systems that run Solaris DiskSuite (SDS) to the Solaris Volume Manager without disturbing or changing the configuration. Upgrades of mirrored root file systems are fully and automatically supported.

    Solaris Volume Manager and a Mirrored boot disk configuration

    • If fewer than 50 precent of the defined metadb replicas are available, Solaris Volume Manager ceases to operate.
    • If fewer than or equal to 50 present of the defined metadb replicas are available at boot time, you cannot boot the system. However, you can boot single-user mode and just use the metadb command to delete ones that are not available.

    To override this behavior you can add the following line to the /etc/system file.

    set md:mirrored_root_flag=1

    This allows you to boot fully with exactly 50 precent of the metadb's but not less than 50 precent.
