About vdisk reconstruction

If one or more disks fail in a redundant vdisk (RAID 1, 3, 5, 6, 10, or 50) and compatible spares are
available, the storage system automatically uses the spares to reconstruct the vdisk. Vdisk reconstruction
does not require I/O to be stopped, so the vdisk can continue to be used while the Reconstruct utility runs.
A properly sized spare is one whose capacity is equal to or greater than the smallest disk in the vdisk. A
compatible spare has enough capacity to replace the failed disk and is the same type (SAS or SATA). If no
compatible spares are available, reconstruction does not start automatically. To start reconstruction
manually, replace each failed disk and then do one of the following:
• Add each new disk as either a dedicated spare or a global spare. Remember that a global spare might
be taken by a different critical vdisk than the one you intended.
• Enable the Dynamic Spare Capability option to use the new disks without designating them as spares.
Reconstructing a RAID-6 vdisk to a fault-tolerant state requires two compatible spares to be available.
• If two disks fail and only one compatible spare is available, an event indicates that reconstruction is
about to start. The Reconstruct utility starts to run, using the spare, but its progress remains at 0% until a
second compatible spare is available.
• If a disk fails during online initialization, the initialization fails. In order to generate the two sets of
parity that RAID 6 requires, the controller fails a second disk in the vdisk, which changes the vdisk
status to Critical, and then assigns that disk as a spare for the vdisk. The Reconstruct utility starts to run,
using the spare, but its progress remains at 0% until a second compatible spare is available.
