Testing enclosure connections 1. Press the power switches at the back of each drive enclosure to On. IMPORTANT: This ensures that the disks in the enclosures have enough time to completely spin up before being scanned by the RAID modules in the controller enclosure. While enclosures power up, their LEDs blink. After the LEDs stop blinking, if no LEDs on the front and back of the enclosure are amber, the power-on sequence is complete and no faults have been detected.
1. From your network administrator obtain an IP address, subnet mask, and gateway address for controller A and controller B. 2. Use the provided micro-DB9 serial cable to connect controller A to a serial port on a host computer. Your package contents include a micro-DB9-to-DB9 serial cable. If necessary, use a DB9-to-DB25 adapter (not included) for connecting the serial cable to a DB25 serial port on the host computer. 3.
6. At the prompt, type the following command to set the values you obtained in Step 1 for each Ethernet management port, first for controller A and then for controller B: set network-parameters ip address netmask netmask gateway gateway controller a|b where: • address is the IP address of the controller • netmask is the subnet mask • gateway is the IP address of the subnet router • a|b specifies the controller whose network parameters you are setting For example: # set network-parameters ip 192.168.0.
1. Attach the rear brackets to the MSA2324 Carrier-Grade (CG). 2. Attach the left bracket assembly to the left rack rail. 3. Attach the right bracket assembly to the right rack rail. 4. Insert cage nuts into the rack holes. 5. Align the MSA2324 CG with the rails, and then slide it into the rack until the ears of the MSA2324CG are about 1 to 2 inches from the rack front rails. 6.

8. Loosely attach the rear brackets to the rear bracket assemblies. 9. Attach the loose end of the ground cable to the front rack ground rail. 10. Verify that the MSA2324 CG is evenly spaced between the right and left rack rails, and then tighten the front and rear bracket screws.
Installing the enclosures
4 Connecting hosts Host system requirements Data hosts connected to MSA2324fc arrays must meet the following requirements: • Depending on your system configuration, data host operating systems may require that multipathing is supported. If fault tolerance is required, then multipathing software may be required. Host-based multipath software should be used in any configuration where two logical paths between the host and any storage volume may exist at the same time.
Two servers/one dual-ported HBA per server/dual path Server 1 Server 2 Connecting switch attach configurations Two servers/two switches Server 1 Server 2 Connecting remote management hosts The management host directly manages systems out-of-band over an Ethernet network. 1. Connect an Ethernet cable to the Ethernet management port on each controller. 2. Connect the other end of each Ethernet cable to a network that your management host can access (preferably on the same subnet).
5 Basic operation Powering on/powering off Before powering on the enclosure for the first time: • Install all hard drives in the enclosure so that the connected host controller can identify and configure them at power-up. • Connect the cables and power cords to the enclosure as explained in the Installation Poster.

8 Troubleshooting Fault isolation methodology The MSA2000 Family storage system provides many ways to isolate faults within the system. This section presents the basic methodology used to locate faults and the associated FRUs.
Correcting enclosure IDs When installing a system with drive enclosures attached, the enclosure IDs might not agree with the physical cabling order. This is because the controller might have been previously attached to some of the same enclosures during factory testing and it attempts to preserve the previous enclosure IDs if possible. To correct this condition, make sure that both controllers are up and perform a rescan using SMU or the CLI.
Are both drive module LEDs off (Online/Activity and Fault/UID)? Answer Possible Reasons Actions Yes • There is no power. • Check that the drive is fully inserted and latched in place, and that the enclosure is powered on. • The drive is offline. • The drive is not configured. Is the drive module Fault/UID LED blinking amber? Answer Possible Reasons Actions No, but the Online/Activity LED is blinking. The drive is rebuilding. No action required. Yes, and the Online/Activity LED is off.
Is a connected port’s Expansion Port Status LED off? Answer Possible Reasons Actions No System functioning properly. No action required. Yes The link is down. • Check cable connections. • Reseat cables. • Replace cables. • In SMU, review the event logs for indicators of a specific fault in a host data path component. Is a connected port’s Ethernet link status LED off? Answer Possible Reasons Actions No System functioning properly. No action required. Yes The link is down.
Is the drive enclosure back panel OK LED off? Answer Possible Reasons Actions No System functioning properly. No action required. Yes The power supply unit or a fan is operating at an unacceptable voltage/RPM level, or has failed. When isolating faults in the power supply, remember that the fans in both modules receive power through a common bus on the midplane, so if a power supply unit fails, the fans continue to operate normally. • Check that the power supply FRU is firmly locked into position.
Controller failure in a single-controller configuration Cache memory is flushed to CompactFlash in the case of a controller failure or power loss. During the write to CompactFlash process only the components needed to write the cache to the CompactFlash are powered by the super-capacitor. This process typically takes 60 seconds per 1 Gbyte of cache. After the cache is copied to CompactFlash, the remaining power left in the super-capacitor is used to refresh the cache memory.
Isolating a host-side connection fault During normal operation, when a controller module host port is connected to a data host, the port’s host link status LED and host link activity LED are green. If there is I/O activity, the host activity LED blinks green. If data hosts are having trouble accessing the storage system, and you cannot locate a specific fault or cannot access the event logs, use the following procedure. This procedure requires scheduled downtime.
Isolating a controller module expansion port connection fault During normal operation, when a controller module’s expansion port is connected to a drive enclosure, the expansion port status LED is green. If the connected port’s expansion port LED is off, the link is down. Use the following procedure to isolate the fault. This procedure requires scheduled downtime. NOTE: Do not perform more than one step at a time. Changing more than one variable at a time can complicate the troubleshooting process. 1.
Sensor locations The storage system monitors conditions at different points within each enclosure to alert you to problems. Power, cooling fan, temperature, and voltage sensors are located at key points in the enclosure. In each controller module and expansion module, the enclosure management processor (EMP) monitors the status of these sensors to perform SCSI enclosure services (SES) functions. The following sections describe each element and its sensors.
