3.0 Initialize Drives The ATTO FastStream allows configuration of storage into DVRAID, JBOD, RAID Level 0, RAID Level 1, RAID Level 1+0, RAID Level 4 or RAID Level 5 with the ability to create multiple partitions. You should first initialize and verify all drives. Before creating any RAID group you should initialize and verify the drives you want in the RAID group to ensure drive integrity. If you do not want to initialize or verify drives now, continue on to Configure Storage into RAID Groups on page 11.
Scanning drive surfaces: read-only drive test The read-only drive test performs a non-destructive scan over the entire surface of each drive to identify bad areas of disk drives and determine read performance. It may be run while data is passing through the FastStream. Running this test may negatively impact performance. Once the read-only test has completed, system operation returns to normal.
4.0 Configure Storage into RAID Groups The ATTO FastStream allows configuration of storage into DVRAID, JBOD, RAID Level 0, RAID Level 1, RAID Level 1+0, RAID Level 4 or RAID Level 5 with the ability to create multiple partitions. RAID is a storage configuration which uses multiple drives to increase capacity, performance and/or reliability.

Time and date: use a remote time server to set the time and time zone, or manually set the time and date. Refer to Date, Time, TimeZone and SNTP in Appendix A, CLI Provides an ASCII-based Interface. Fibre Channel: change the data rate or the connection mode for each FC port.
6.0 Monitor Storage, Configurations You may determine the performance of drives attached to the FastStream using various displays and tests in ExpressNAV Storage Manager. The following instructions assume you have already set up at least one RAID group. The ATTO FastStream collects various metrics to measure performance for physical drives attached to the FastStream during normal system operation and drive initialization and verification.
Configuration Display page Clicking on Details from the Health and Status Monitor page gives you added information about various aspects of the FastStream and attached storage. Click on the arrow next to the group you wish to view.
• Informational: information which you may want to know but which probably does not require action: only information messages are sent • All: warnings, critical events and informational messages are sent • None: no Emails are sent You may send Emails to up to five Email addresses and designate which conditions prompt each Email notification. For example, a recipient with a critical severity level only receives critical messages and not warning or informational messages.
Verifying storage 6 CAUTION Data may be erased during this process. Back up your data before selecting Commit. You may verify the status of storage which does not belong to a RAID group (unattached storage) to identify drive issues after drives have been initialized. If the verify operation detects an error, the FastStream tries to re-initialize the drive, erasing information stored on the drive. Be sure to back up data before performing verification.
7.0 Modify Storage Use the ExpressNAV Storage Manager to replace a failed drive, add new drives or redesign RAID configurations. You may modify various aspects of storage using the Manage Menu found by clicking on the tab on the left hand side of the ExpressNAV Storage Manager. Be cautious when deleting storage or rearranging storage configurations because data could be compromised or lost.

EventLog FCHard Regulates event logging. When enabled, the unit records various system events to the event log. Regulates Fibre Channel hard address assignment. When enabled, the unit tries to use its internal hard address as its address on the Fibre Channel loop. Under soft addressing, the unit loop address is assigned during loop initialization.
FCTargets (FS 7700 only) IPAddress Lists all target devices available on the Fibre Channel port with the index specified by fp. If no port index is specified, then all target devices on all Fibre ports are displayed. A port-unique index is assigned to each target which is used with the fp to specify a Fibre Channel target for a subsequent Route CLI command. Controls the current IP address of the Ethernet port(s) on the unit.
MaxOpTemp PartitionMerge Regulates the maximum operating temperature of this unit in degrees Celsius. Valid entries are between 55 and 70 degrees. Combines the specified contiguous partitions into one partition. Partition index is the index of a partition to merge, along with a number of contiguous partitions to merge to that index. All indicates that all partitions in the RAID group are merged into a single Virtual Disk. The RAID group must not be in a NEW state.
ReadOnlyPassword RGAutoRebuild Specifies a password which allows only read and no writes. It is case sensitive, 0 to 32 characters, and cannot contain spaces. An empty password can be configured by not specifying one. Uses drives assigned as Hot Spares, then available drives, as automatic replacements for any member that fails. Default: Password set ReadOnlyPassword ReadOnlyUsername Specifies the user name which allows only read and no writes.
RGHaltConversion RGSpanDepth Stops the conversion of the specified RAID group. Regulates the span depth on the specified RAID group. The RAID group must be of type RAID 0, 1, 4, 5 or 1+0. RGHaltConversion [group name] RGHaltErase Stops the erase on the specified RAID group. RGHaltErase [group name] RGHaltRebuild Stops the rebuild(s) on the specified RAID group. If no member index is specified, all rebuilds on that RAID group are stopped.
RouteDisplay SNTPServer Displays a combined list of host protocol address to target destination device mappings. Controls or displays the main IP address the client uses to retrieve the SNTP time and date. If FCMultiNode is disabled:RouteDisplay FC If FCMultiNode is enabled: RouteDisplay FC Default: 192.43.244.18 set SNTPServer [xxx.xxx.xxx.xxx] SaveConfiguration Restart command required get SNTPServer SASTargets Lists the physical devices that are connected to all SAS ports.
VirtualDriveInfo WrapEventLog Displays characteristics and statistics for all available virtual drives or any available virtual drive identified by its virtual drive ID. Controls EventLog output wrapping. When enabled, the unit logs up to 2048 event entries before overwriting the first entries. When disabled, the unit stops logging event entries at buffer full.
Appendix B Design RAID Groups The ATTO FastStream provides instant hardware data protection and intelligence to existing storage independent of the storage type. CAUTION Exhibit A-2 JBOD: Just a Bunch of Disks: no redundancy; each disk is treated independently JBOD RAID improves data accessibility and reliability during normal operations, however, you still need a good backup strategy for long-term protection of your data. To set up RAID groups refer to Configure Storage into RAID Groups on page 11.
RAID Level 1 RAID Level 1 ensures the security of data by writing the exact same data simultaneously to two different drives. With RAID Level 1, the host sees what it believes to be a single physical drive of a specific size: it does not know about the mirrored pair. This application is used for critical data which cannot be at risk to be lost or corrupted due to the failure of a single drive. The ATTO FastStream supports an even number of 2 to16 drives per RAID Level 1 group.
