Powering on or off, or rebooting storage systems with modular components
Some storage systems are comprised of modular components, that may include:
• Disk enclosure
• Server blades enclosure
• System controller
The P4800 is an example of a storage system that is comprised of modular components.
Power on the components in the following order:
1. Disk enclosure.
2. Server blades enclosure or system controller.
Allow up to 6 minutes for the system controller to come up completely and be discovered by
the CMC. If the CMC cannot find the storage system after 6 minutes, contact Customer Support.
3. If you do not power on the disk enclosure first, the Storage System Details tab shows the status
with No Formatted Devices Available.

When powering off the storage system, be sure to power off the components in the following order:
1. Power off the server blades enclosure or system controller from the CMC as described in
“Powering off the storage system” (page 24).
2. Manually power off the disk enclosure.
When you reboot the storage system, use the CMC, as described in “Rebooting the storage system”
(page 23). This process reboots only the server blades enclosure or the system controller.
Rebooting the storage system
1. Select a storage system in the navigation window and log in.
2. Click Storage System Tasks on the Details tab and select Power Off or Reboot.
3. In the minutes field, enter the number of minutes before the reboot should begin.
Enter any whole number greater than or equal to 0. If you enter 0, the storage system reboots
shortly after you confirm the reboot.
NOTE: If you enter 0 for the value when rebooting, you cannot cancel the action. Any value
greater than 0 allows you to cancel before the reboot actually takes place.
