How to switch off storage IBM DS ? – Server Fault

Read any additional safety information that comes with your system or optional device before you install the device. If your system has a module containing a lithium battery, replace it only with the same module type made by the same manufacturer. Use safe practices when lifting. The power control button on the device and the power switch on the power supply do not turn off the electrical current supplied to the device.

The device also might have more than one power cord. To remove all electrical current from the device, ensure that all power cords are disconnected from the power source. Refer to the information that is provided with your device for electrical specifications. Ensure that the rack is secured properly to avoid tipping when the server unit is extended. The following label indicates moving parts nearby. Do not place any object on top of rack-mounted devices. This equipment ibk designed to permit the connection of the lbm conductor of the dc supply circuit to the earthing conductor at the equipment.

If this connection is made, all of the following conditions must be met: Multiple devices extended into the service position can cause your rack cabinet to tip. Intra-building wiring cabling must be shielded and grounded at each end when used with the storage device.

The intra-building ports of this equipment must not be metallically connected to the interfaces that connect to the OSP outside plant or its wiring. DS storage subsystem is not intended to be manul directly or indirectly by any means whatsoever to interfaces of public telecommunication networks. DS is a 2U rack-mountable storage subsystem that supports up to two redundant, dual-active RAID storage controllers.

Each controller contains 1 GB of cache memory that can be upgraded to 2 GB. Each statement is followed by a reference number that you can use to locate the corresponding statement in your language in the IBM Systems Safety Notices document.

Each controller supports one v Minimum configuration: The storage subsystem components and configurations are explained in this topic. The DS storage subsystem controller cache size, partitions, and other features vary depending on the model and optional devices.


Table 2 shows the DS models and options available at the time of publication. Contact your IBM marketing representative or authorized reseller for more information about models and options.

To obtain this optional capability, you must purchase a 96 to drive expansion premium feature. Operating-system support This topic discusses the operating systems are supported for the DS storage subsystem. The following operating systems are supported for host servers that nanual mapped LUNs created in the DS storage subsystem with storage enclosures: On the next page, click register now.

Download the latest version of the Storage Manager software, DS storage Two dc power supply and fan units machine type models C4T and E4T.

Disk drives and bezels An in-depth look at how disk drives and manuall are set up in the DS storage subsystem. The hot-swap drive bays that are accessible from the front of the DS storage subsystem and EXP storage enclosure are shown in Figure mnual. Left-side bezel Right-side bezel and bottom shelf The right-side bezel and bottom shelf contain the drive identification information. The storage management software automatically sets the enclosure ID for the controllers.

You can change the enclosure ID through the Storage Manager software only. There are no switches on the DS chassis to manually set the enclosure ID. Both controller enclosure IDs are identical under normal operating conditions. Rear view, single-controller model shown without an optional host port adapter Note: Press this button if you have forgotten the password. Figure 11 and Table 3 on page 15 below show the location and describe the function of the dc power supply connector pins.

Software and firmware support code upgrades To enable support for the DS storage subsystem, you must ensure that the system software and firmware are of the latest versions. Determining firmware levels To determine the firmware levels of the DS storage subsystem, the connected storage enclosures, and the installed drives, use the Storage Manager software that is used to manage the DS storage subsystem.

In the Subsystem Management window, click the Summary tab.

The total weight of the storage subsystem and storage enclosure depends on the number of installed components. Table 4 lists the maximum and empty weights for the DS storage subsystem and EXP storage enclosure in different configurations. Table 7 on page 20 lists the acceptable temperature and humidity ranges for the storage subsystem in typical Information Technology IT or office environments. This refers to a total of hours in any given year, but no more than 15 occurrences during that one-year period.

Electrical requirements The electrical requirements to operate the DS storage subsystem are specified in this topic. Site wiring and power The site wiring and power manuao to operate the DS storage subsystem are specified in this topic. Air enters at the front of the DS storage subsystem and EXP storage enclosure and leaves at the back. Allow at least 30 inches in front of the DS storage subsystem and EXP storage enclosure and at least 24 inches at the rear for service clearance, proper ventilation, and heat dissipation.


Also, all the gaps in the front of the racks must maual sealed, including the gaps between the storage subsystems. The DS storage subsystem ac power models do not have region-specific power cords. You must obtain the IBM-approved ac power cords for your region.

Prepare the installation site. Install and secure the DS chassis and components in the rack.

Install the storage enclosure in the rack, if you are installing one or more storage enclosures. This topic prepares you for the DS storage subsystem and the EXP storage enclosure installation. Before you install the DS storage subsystem, create a detailed plan of how the device amnual be used in the storage configuration. The plan should include RAID levels, failover requirements, operating systems that are to be used, and total storage capacity requirements.

Cabling the storage subsystem and storage enclosure Ensure that it locks into place. To remove a mini-SAS cable, complete the following steps: Hold the blue plastic tab on the mini-SAS connector and gently pull the tab to release the locking mechanism.

Blue plastic tab Figure Removing a mini-SAS cable 2. As you pull the tab, pull out amnual connector to remove it from the port. The operational or redundant loop performance is not affected when you install or remove an SFP module. SFP module that is connected to a 4-Gbps-capable port will limit the speed of that port to a maximum of 2 Gbps. Unlock the SFP module latch: Wire Protective module Figure Save the protective caps for future use.

Fiber-optic cable Protective cap Figure Removing fiber optic cable protective caps 4. The cable connector is keyed for correct installation. At the end of the cable that connects into the LC connector end of the LC-SC cable adapter, press down and hold the lever to release the latches.

Figure 35 on page 45 shows the location of the lever and latches. ESMs each, complete the following steps: Connect one EXP storage enclosure to controller A: Repeat steps 2a and 2b for each EXP storage enclosure that you add. Connect the last EXP manuall enclosure in the chain to controller B: The storage enclosures that are connected to this connector form a drive channel.

You can install a maximum of 96 drives in one drive channel.

In a dual-controller DS, one drive channel from each controller combines to form a redundant drive-channel pair. One dual-controller DS and one storage enclosure: To cable a dual-controller DS to a storage enclosure, connect them as shown in Figure 40 on page A dual-controller DS and two storage enclosures One dual-controller DS and up to eight storage enclosures: To cable a dual-controller DS and up to eight storage enclosures, connect them as shown in Figure 42 on page For more information about installing a second De3512, see the Installation Guide that is shipped with iibm storage enclosure.
