PreferredPath
If you select the Manual setting for PreferredPathMode (on page 79), use the PreferredPath
command to specify the path for I/O to the logical drive on a redundant controller in active/active mode.
The default setting for this option is 1. With this setting, the controller in chassis slot 1 is the preferred
controller for I/O to the logical drive. If you select 2, the controller in chassis slot 2 becomes the preferred
controller for the logical drive.
To determine the chassis slot numbers, use the show command on a controller that supports redundant
controllers.
RAID
The value that you enter for this option specifies the RAID level of the logical drive.
•
When the Action mode is Configure, and the Method mode is Auto, ACU automatically selects the
highest RAID level that the controller and drive configuration can support except RAID 50 or RAID 60.
To specify RAID 50 or 60 for a controller that supports either of these RAID levels, use the Custom
setting. In this case, you must also specify the number of parity groups ("NumberOfParityGroups" on
page 83).
•
When the Action mode is Reconfigure, the default value is the existing RAID level for that logical drive.
If you specify a different RAID setting, then ACU either ignores the new setting (when Method mode is
Auto), or attempts to migrate the logical drive to the specified RAID level (when Method mode is
Custom).
ACU supports the following values for RAID levels:
•
60—RAID 60
•
50—RAID 50
•
ADG—RAID ADG is the equivalent of RAID 6
•
6—RAID 6
•
5—RAID 5
•
4—RAID 4
•
10ADM—RAID 1 with 3-way mirroring
•
10—RAID 10 (mirroring with 2 disks)
•
1ADM—RAID 1 with 3-way mirroring
•
1—RAID 1 (mirroring with 2 disks)
•
0—RAID 0
Some RAID levels require SAAP
Renumber
This option renumbers the logical drive to N.
Typically used after a Join command, this option ensures the proper logical volume numbering is set, for
example, the boot volume is ID 1.
