Chapter 4 Troubleshooting Indicators Figure 60 TC2201E LEDs Ethernet Activity iSCSI Link Status Power/Fault SCSI Activity for Bus 0 iSCSI Activity SCSI Activity for Bus 1 The LED functionality of the TC2201E is detailed below: 88 • Power and Fault (Pwr)—This indicator is a bi-color LED. When green, this indicator shows that power is currently active. Lack of power indication suggests that the unit is turned off, a problem with the power supplied to the unit, or an internal problem with the unit.
Chapter 4 Troubleshooting Basic Verification connection or configuration. Verify the network connection and configuration. The port must be connected to a 10/100BaseT Ethernet network to function properly. Basic Verification Serial Port Problems 4 Verify SCSI Bus Configuration 4 4 If you experience trouble communicating with the serial port, verify the configuration of the host terminal or terminal emulation program.
Chapter 4 Troubleshooting Basic Verification • Cabling—Check SCSI cables to verify they are functional. SCSI rules for total length, distance between devices, and stub length must be adhered to. Connections should also be checked and reseated if necessary. • SCSI Devices—Verify that the SCSI devices on a particular SCSI Bus can be seen in the by the TC2201E. Check the Discovery page to verify visibility of devices.
Chapter 4 Troubleshooting Basic Verification Verify Mapping 4 Verify that all desired devices have been discovered and mapped. If using Indexed mapping, try swapping to Auto-assigned to see if this solves the problem. Verify Devices 4 It may be useful to connect the SCSI target devices you are attempting to use to the native SCSI interface to verify that the devices are functional. SCSI target devices can be connected to a host SCSI bus to verify they are functional.

Procedure E: Bakbone NetVault 5 1 When the library is configured, click on NetVault Device Management (as shown in figure 64).
Procedure F: HP Data Protector Figure 64 Netvault Device Management Procedure F: HP Data Protector 5 In order to increase the maximum block size on a Windows Media Agent client, you must first modify its Registry. After modifying the Registry, restart the computer. Drivers read MaximumSGList at boot time.
Procedure F: HP Data Protector 6 Start the regedit32 and add a DWORD value in the following Registry key: \\HKEY_LOCAL_ MACHINE\SYSTEM\CurrentControlSet\Services\aic78 xx\Parameters\Device0\MaximumSGList 7 Use the following formula to calculate the value of the MaximumSGList: MaximumSGList = (BlockSize/4096)+1 For example, the MaximumSGList value for a 256k block size is 65, as follows: MaximumSGList = (265k/4k) + 1 = 64 + 1 = 65 If you have, for example, three aic78xx based SCSI channels on your system, c
Procedure G: CommVault Galaxy Figure 65 HP Data Protector (Advanced Options) Procedure G: CommVault Galaxy 5 To increase block size, do the following. 1 Using the CommVault Resource Pack CD, navigate to the folder titled setFlushBlockSize. 2 Copy SetFlushBlockSize executable to the \Base directory. 3 Navigate to this program SetFlushBlockSize.exe and double click to run.
Procedure G: CommVault Galaxy 4 Select the desired Recording format and change the Flush Block Size using the drop down list (as shown in figure 66) of values - 8 KB, 16 KB, 32 KB, 64 KB, 256 KB. Figure 66 CommVault Galaxy To increase chunk size, do the following. Note: The default chunk size that galaxy uses for granular backups is 2 Gb. The size for database backups is 8. Higher chunk size will give you better throughput. Recommended values are: 8 Gb, 16 Gb or 32 Gb. For Galaxy 5.
Procedure G: CommVault Galaxy 5 Select a chunk size from the second drop down list. The list provides selections of 128 MB, 256 MB, 512 MB, 1 GB, 2 GB, 4 GB, 8 GB, 16 GB, 32 GB; by default, it shows the current value for the selected appType. For Galaxy 5.9 Users: 1 Open the CommCell Console For Java GUI. 2 Open Control Panel and then click on Job management. 3 Click on the Advanced tab (as shown in figure 67). 4 Modify the chunk size for different application types and click OK to confirm changes.
Procedure G: CommVault Galaxy 172 Quantum TC2201E User’s Guide
Glossary A adapter A printed circuit assembly that translates data between the iSCSI host processor’s internal bus and a different bus, such as SCSI. address See SCSI Addressing. addressing mode Used to create a mapping table that maps devices on the SCSI bus to Fibre Channel logical units. area The second byte of the N_Port Identifier. authentication A process of identification, usually based on a username and password. auto-assigned mapping A menu item.
Glossary B baud A unit of signaling speed, expressed as the maximum number of times per second the signal can change the state of the transmission line or other medium (units of baud are sec-1). Note: With Fibre Channel scheme, a signal event represents a single transmission bit. bus A means of transferring data between modules and adapters or between an adapter and SCSI devices. For a SCSI bus definition, see SCSI Bus. C channel A general term for a path on which electronic signals travel.
Glossary E Ethernet MTU Maximum Transmission Unit, the largest physical packet size, measured in bytes, that a network can transmit. Any messages larger than the MTU are divided into smaller packets before being sent. exchange A iSCSI term for the basic mechanism used for managing an operation. An exchange identifies information transfers consisting of one or more related nonconcurrent sequences that may flow in the same or opposite directions, but always in half duplex mode.
Glossary H host bus adapter (HBA) See iSCSI Adapter. HVD High Voltage Differential I ID Numerical identifier indexed addressing A menu name. It allows for generic Fibre Channel host bus adapters to access SCSI devices attached to the TC2201E using a table which is indexed by sequential LUN values. initiator A device (usually a host system) that requests an operation to be performed by another device known as a target (usually a peripheral).
Glossary iSNS iSNS allows the administrator to go beyond a simple device-bydevice management model, where each storage device is manually and individually configured with its own list of known initiators and targets. Using iSNS, each storage device subordinates its discovery and management responsibilities to the iSNS server. The iSNS server thereby serves as the consolidated configuration point through which management stations can configure and manage the entire storage network.
Glossary motherboard The main PCA of the TC2201E that provides a physical and logical connection between Fibre Channel and SCSI devices. multiplexer A device that allows two or more signals to be transmitted simultaneously on a single channel. O offline Taking the TC2201E offline indicates that all SCSI and iSCSI adapters in the TC2201E are offline. Taking a SCSI adapter offline means ending inputs/outputs and suspending all transactions going from the TC2201E to the specified SCSI devices.
Glossary processor Contains the arithmetic and logic, control, and internal memory units that control the TC2201E. R reset SCSI For a specific SCSI bus, the host clears all inputs and outputs and then resets the bus and all the devices connected to it. router An intelligent device within the SAN (storage area network) infrastructure that can handle multiple protocols, such as Fibre Channel and SCSI. The routing decision is based on paths between address mappings among dispersed initiators and targets.
Glossary SCSI addressing A SCSI adapter supports up to 16 devices, including itself. Each device has its own unique SCSI address. The SCSI address of a device dictates the device’s priority when arbitrating for the SCSI bus. SCSI address “7” has the highest priority. The next highest priority address is “6” followed by 5, 4, 3, 2, 1, 0, 15, 14, 13, 12, 11, 10, 9, 8, with “8” being the lowest priority address. The narrow SCSI adapter is factory set to address 7.
Glossary target A device (usually a peripheral) that responds to an operation requested by an initiator (usually a host system). Peripherals are targets, but for some commands (for example, a SCSI COPY command), the peripheral may need to act temporarily as an initiator. terminator block/ termination An electrical connection at each end of the SCSI bus composed of a set of resistors (or possibly other components).
