Schedule downtime

A conversion includes downtime for applications using Solaris Volume Manager volumes during the doconvert, reboot, and change volume references tasks and downtime for the system during the reboot. A second reboot happens automatically if a root device hosts Solaris Volume Manager objects or is a Solaris Volume Manager metadevice.

The doconvert utility takes about a minute unless the conversion includes RAID-5 volumes. RAID-5 conversions take about a minute for each megabyte of RAID-5 data. The total downtime to expect for a conversion is the sum of the following times:

• Approximately one minute to run doconvert.
• The time needed for one or two system reboots.
• Approximately one minute for each megabyte of RAID-5 data if RAID-5 volumes are included.
• The time needed for changing volume references in applications.
