PS6210 Hardware Owner's Manual
Enabling the Standby Feature
To use the standby button, a group administrator must enable the feature in the Group Manager GUI or
CLI.
Enabling the use of the button applies groupwide; that is, it allows you to press the button to shut down
any member (array) that has the standby button (PS4100, PS4110, PS6100, PS6110, and PS6210 array
models). You do not need to enable use of the button on each member separately.
Only a user with group administrator privileges can enable the standby feature on the group.
However, anyone can press the button, and the group cannot determine who put the array into
standby on/off mode. Therefore, group administrators should consider their environment's security
concerns before enabling this feature.
Using the Standby On/Off Button
After the feature is enabled groupwide, you can use the Standby On/Off button on either control
module of any applicable member to shut down the array quickly without using the Group Manager
GUI or CLI.
You must press in and hold the Standby On/Off button for at least two (2) seconds to shut down the
member to the standby state. To fully shut down the array, turn off the switches on the power supply
and cooling modules.
To turn the member back on, press and hold the Standby On/Off button again (and ensure the power
supply switches are turned back to the on position).
Important Considerations
Use the Standby On/Off button only when you must shut down a member fast, in situations where you
do not have access to the Group Manager GUI or CLI. For example, you discover a problem in your
lab environment, such as high temperature or a water leak, that might damage the array.
In standby mode, all volumes that use space on that member or that are bound to that member
become unavailable. All operations on the member are suspended, no I/O activity to or from the
member occurs, and the member's firmware is not running.
Using the Standby On/Off button on one member does not affect any other group members, with the
exception of the Group Lead member. When the group lead member is in standby mode, it takes a few
minutes for the group lead to fail over to another member. You must press the standby button on each
member to restore power to the member that is in standby mode. Group members that do not have the
standby button remain online; to shut them down, you must use the GUI or CLI.
Replacing a Control Module
If a control module fails, remove it and replace it with a functioning control module, as described in
this section.
You will also need to temporarily remove a control module when you want to replace its microSD
card. Refer to
Replacing the MicroSD Card on page 24
card.
You can partially or completely remove a control module without shutting down the array if the
remaining control module has at least one connected and functioning network interface. The
procedures for doing this type of control module replacement are described in the section that follows.
