9.
If you allocated log devices to the pool, enter set log_profile= and set the log
profile to either log_mirror or log_stripe. Use log_mirror if the pool now contains
an even number of log devices.
Caution - A double failure can cause loss of data from a log in a striped configuration. It is
highly recommended to configure a mirrored log profile for added redundancy. For more
information, see “Data Profiles for Storage Pools” on page 111.
hostname:configuration storage (pool1)> set log_profile=log_mirror
Note - If you allocated cache devices to the pool, the profile is always striped.
