First a little background: I'm working with an AIX 6.1 TL05 running two mirrored SAS disks (rootvg) and four SSDs (appvg)
All four SSDs belong to appvg and are setup to mirror as follows:

hdisk5 --> hdisk7 (containing database fs)

metaparam
metaparam(1M) System Administration Commands metaparam(1M)NAME
metaparam - modify parameters of metadevices
SYNOPSIS
/usr/sbin/metaparam -h
/usr/sbin/metaparam [-s setname] [ concat/stripe or RAID5 options] concat/stripe RAID
/usr/sbin/metaparam [-s setname] [ mirror options] mirror
DESCRIPTION
The metaparam command is used to display or modify current parameters of metadevices.
If just the metadevice is specified as an argument to the metaparam command, the current settings are displayed.
The metaparam command enables most metadevice (volume) parameters to be changed. Only the interlace value cannot be changed by metaparam,
because it is established when the metadevice is created and cannot be changed thereafter.
OPTIONS
Root privileges are required for all of the options.
The following options are supported:
-h Displays usage message.
-s setname Specify the name of the diskset on which metaparam works. Using the -s option causes the command to perform its administra-
tive function within the specified diskset. Without this option, the command performs its function on local metadevices.
CONCAT /STRIPE OR RAID5 OPTIONS
-h hot_spare_pool | none Specifies the hot spare pool to be used by a metadevice. If none is specified, the metadevice is disassoci-
ated with the hot spare pool assigned to it. If the metadevice is currently using a hot spare, then meta-
param cannot replace the hot spare pool.
concat/stripe | RAID Specifies the metadevice name of the concatenation, stripe, or concatenation of stripes, or of the RAID5
metadevice.
MIRROR OPTIONS -r roundrobin | geometric | first Modifies the read option for a mirror. The -r option must be followed by either roundrobin, geomet-
ric, or first. roundrobin, which is the default action under the metainit command, specifies read-
ing the disks in a round-robin (load balancing) method. geometric allows for faster performance on
sequential reads. first specifies reading only from the first submirror.
-w parallel | serial Modifies the write option for a mirror. The -w option must be followed by either parallel or
serial. parallel, the default action under the metainit command, specifies that all writes are par-
allel. serial specifies that all writes are serial.
-p pass_number A number from 0-to-9 that specifies the order in which a mirror is resynced during reboot. The
default is 1. Smaller pass numbers are resynced first. Equal pass numbers are run concurrently. If
0 is used, the mirror resync is skipped. 0 should only be used for mirrors mounted as read-only, or
as swap.
mirror Specifies the metadevice name of the mirror.
EXAMPLES
Example 1: Associating Hot Spare Pool with RAID5 Metadevice
This example associates a hot spare pool, hsp005, with a RAID5 metadevice, d80.
# metaparam -h hsp005 d80
Example 2: Changing Read Option to Geometric
This example changes the read option on a mirror d50 from the default of roundrobin to geometric.
# metaparam -r geometric d50
EXIT STATUS
The following exit values are returned:
0 Successful completion.
>0 An error occurred.
