Shutting Down; Testing Event Notification; Expanding A Vdisk - HP P2000 G3 Reference Manual

Shutting down

Shutting down the Storage Controller in a controller module ensures that a proper failover sequence is
used, which includes stopping all I/O operations and writing any data in write cache to disk. If the
Storage Controller in both controller modules is shut down, hosts cannot access the system's data. Perform
a shut down before removing a controller module or powering down the system.
CAUTION: You can continue to use the CLI when either or both Storage Controllers are shut down, but
information shown might be invalid.
To perform a shut down
1. In the Configuration View panel, right-click the local system and select Tools > Shut Down or Restart
Controller.
2. In the main panel, set the options:
• Select the
• Select whether to restart the processor in controller A, B, or both.
3. Click Shut down now. A confirmation dialog appears.
4. Click Yes to continue; otherwise, click No. If you clicked Yes, a second confirmation dialog appears.
5. Click Yes to continue; otherwise, click No. If you clicked Yes, a message describes shutdown activity.
NOTE:
in the Windows event log: Initiator failed to connect to the target.

Testing event notification

You can send a test message to verify that email addresses and/or SNMP trap hosts are properly
configured to receive event-notification messages. In order to receive messages, the email or SNMP
configuration settings must include a notification level other than "none (disabled)."
To send a test message
1. In the Configuration View panel, right-click the local system and select Tools > Send Test Notification.
2. Click Send. If the task succeeds, verify that the test message reached the destinations.

Expanding a vdisk

You can expand the capacity of a vdisk by adding disks to it, up to the maximum number of disks that the
storage system supports. Host I/O to the vdisk can continue while the expansion proceeds. You can then
create or expand a volume to use the new free space, which becomes available when the expansion is
complete. You can expand only one vdisk at a time. The RAID level determines whether the vdisk can be
expanded and the maximum number of disks the vdisk can have.
NOTE: Expansion can take hours or days to complete, depending on the vdisk's RAID level and size, disk
speed, utility priority, and other processes running on the storage system. You can stop expansion only by
deleting the vdisk.
Before expanding a vdisk
Back up the vdisk's data so that if you need to stop expansion and delete the vdisk, you can move the data
into a new, larger vdisk.
