Disallowing member firmware downgrades
If the Disallow downgrades option is active, the group is not using all features of the installed firmware. You must
disallow firmware downgrades to use the features in an updated firmware release.
Requirement: Before you disallow firmware do
wngrades, make sure all group members are running the same
firmware version.
1. Click
Group, then Group Configuration, and then the Advanced tab.
2. Click
Disallow downgrades in the Member Firmware panel. (Alt+D).
3. Confirm that you want to disallow downgrades.
Removing a member from the group
You can remove a member from a multi-member group while the group is online and data stays available. The
group moves any volume data from the member you are removing to the remaining pool members. Removing a
member decreases the overall storage capacity of the group and also decreases the capacity of the storage pool to
which the member belongs.
Note: You cannot remove a member from the group unless th
e remaining pool members have enough space to
store the data from the member that you want to remove.
Members you remove from a group are automatically reset to the factory defaults. Previous group, me
mber, and
volume information, as well as any volume data on the member, are removed.
Removing a member from a group can be a long operation, de
pending on the amount of data the group must move
to the remaining pool members. While data is moving, the member status is
vacating-in-progress.
1. Click
Group, then expand Members, then select the member name, and then click Delete member.
If you receive a “vacate failed” message, the member is offline.
2. Confirm you want to delete the member.
Shutting down a member
For maintenance purposes, you might need to cleanly shut down a member. Shutting down a member has no effect
on member, volume, or group configuration information or volume data stored on the member.
Shutting down a member does not turn off array power. To turn off
array power, turn off all power switches on the
array after the shutdown completes.
Note: To restart a member that you shut down, turn on all power switches.
1.
Click
Group, then expand Members, then select the member name, and then click the Service tab.
2. Click
Shutdown in the lower part of the GUI window.
3. In the Member Shutdown confirmation dialog box, enter you
r group administrator account password and click
OK.
