Chapter 3. Operating SAS/SATA MyStorage management software This chapter provides an overview of how to operate the MyStorage management software for SAS/SATA expanders and host adapters. Storage topology: SAS/SATA controllers This function provides a view of the attributes of any SAS/SATA host adapter that is installed in the server or in a remotely managed server. After selecting the Storage Topology icon, highlight a host adapter. The MyStorage management software provides detailed information in a series of four tabs. These four tabs provide the following read-only information about the host adapter. v Host adapter information v Adapter phy information v Advanced adapter information v Advanced configuration SAS/SATA host adapter information This tab gives the basic information about the adapter, such as the host name of the computer on which the adapter is installed, manufacturer of the SAS adapter, driver version, managing BIOS version, firmware version, chip name, chip revision, board name and serial number about the adapter. Copyright IBM Corp. 2006 11

SAS/SATA adapter phy information This tab gives information about the Phy Speed, the address of the port on which the phy is connected, the routing type, and whether an expander or a storage disk is connected to it. If the attached device is an end-device, this panel also shows the Target ID of the end device. Phy speed The phy speed is 3 Gbps if connected to a SAS end device or an expander phy. Phy speed is 1.5 Gbps if connected to a SATA device. SAS address The SAS address is a unique worldwide name assigned to a SAS initiator port, SAS target port, expander device, SAS initiator device, or SAS target device. Phy routing There are three types of phy routing: table routing, direct routing and subtractive routing. A brief description of the different types of routing are in the following list: v Direct routing method: The method the expander connection manager uses to establish a connection with an end device. v Table routing method: The method the expander connection manager uses to route connection requests to an expander device using an expander routing table. v Subtractive routing method: The method the expander connection manager uses to route connection requests not resolved using the direct routing method or table routing method to an expander device. 12 LSI Logic MyStorage Management Software: User s Guide for IBM SAS Controllers

Advanced SAS/SATA adapter information This tab gives the information about the advanced settings of the adapter. Information like adapter address, adapter chipset or name, number of supported buses and the maximum number of supported devices is provided by this tab. Chapter 3. Operating SAS/SATA MyStorage management software 13

Advanced configuration This tab provides information about the port width of the phys. Adapter reset and phy resets can also be performed under this tab. Port width of phys Port width of phys can be narrow or wide. A port is narrow when only one phy connects two devices, for example, one adapter and one expander is connected to each other by one phy. A port is wide when two or more phys connect from the adapter to an expander or an expander to an expander. Note that end devices or hard disk drives are always connected through a narrow port, for example, one single phy connects it to the adapter or expander. Adapter reset The Adapter Reset setting performs a complete host adapter reinitialization. The effect is to cycle power on the host adapter. Phy reset The Phy Reset setting generates a phy reinitialization sequence. This has an effect similar to unplugging the cable and reinserting it. In this option, the host connection that has to be reset can be selected. If the selected phy is among any one of the wide port, it resets all the phys of the wide port. 14 LSI Logic MyStorage Management Software: User s Guide for IBM SAS Controllers

Storage Topology: SAS/SATA expanders topologies The MyStorage management software provides information about an expander under two tabs: Expander Info and Expander Phy Info. After you highlight the expander, navigate the two tabs to view read-only information about that device. Expander information tab This tab provides information about the number of phys, table entries, port width, and parent type. Number of Phys This is the number of phys being reported by the device. Port Width The port width indicates whether the port is wide or narrow. A value of 1 indicates a narrow port. A value of 2 or more indicates a wide port. Expander phy information tab This tab gives information about the Phy connected to the expander. You can change the phy number from the Select Phy list. The Expander phy information tab contains the following information: Maximum Link Rate Maximum link rate programmed in the Phy (usually 3 Gbps) Minimum Link Rate Minimum link rate programmed in the Phy (usually 1.5 Gbps) Chapter 3. Operating SAS/SATA MyStorage management software 15

Current Link Rate The current link rate depends on the type of end device or hard disk drive that is connected to the adapter or expander. If a SAS end device or phy of another expander is connected to the adapter, the Current Link Rate is set to 3 Gbps. In case of a SATA-type end device, the Current Link Rate is set to 1.5 Gbps. Routing Attribute This gives the type of routing attribute for a port. As stated previously, it might be Table Routing, Direct Routing, and Subtractive Routing. SAS Address This is the address of the SAS port under consideration. Attached Device Type This is the device type connected to the specific port. It states whether the device is an expander or a hard disk end device. SAS Address of the Attached Device This is the address of the device connected to the SAS port under consideration. 16 LSI Logic MyStorage Management Software: User s Guide for IBM SAS Controllers

Typical SAS/SATA topologies SAS domains support a wide variety of topologies. The following illustration shows two different SAS host bus adapters connected to a single expander. Chapter 3. Operating SAS/SATA MyStorage management software 17

The following illustration shows a configuration called cascaded expander topology. In this case, the drives are connected through an expander, then through another expander to the SAS controller. 18 LSI Logic MyStorage Management Software: User s Guide for IBM SAS Controllers

Storage Topology: storage devices The MyStorage management software provides information about a storage device (target) in a single tab. After you highlight the storage device, you can view read-only information about that device. This tab gives you detailed information about the target storage device including manufacturer, hardware name, serial number, capacity, connector type or protocol (SAS, SSP, or SATA, depending on the disk type). The most important information is the Target ID and the Attached Phy. The Target ID defines the SCSI address of the device. The Attached Phy defines the phy number of the expander or the adapter to which the end disk is connected (see the following illustration). The following illustration shows the storage target device information. Chapter 3. Operating SAS/SATA MyStorage management software 19

RAID topology: SAS/SATA controller This tab enables you to view the RAID topology configured on the SAS controller. The SAS controller supports RAID 0, RAID 1, and RAID 1E. This tab gives the basic information about the different RAID capabilities supported by the SAS controller: striping, mirror, and mirror enhanced. It also gives information about the number of RAID volumes configured, the number of active RAID volumes, and the number of inactive RAID volumes. 20 LSI Logic MyStorage Management Software: User s Guide for IBM SAS Controllers

RAID volume information This tab provides the basic information about a particular RAID volume. The following illustration shows examples of the values that are typically displayed for an active RAID volume. The RAID Volume Information tab has the following choices: RAID Volume Target ID This is the SCSI target ID of the RAID volume visible from the operating system. Capacity This provides the total volume size for the RAID volume. Stripe Status Size This is the stripe size of the disk block that is used for striping in an Integrated Striping (IS) or Integrated Mirroring Enhanced (IME) configuration. In an Integrated Mirroring (IM) configuration, this value is 0. Status provides the state of the RAID volume. States can be OK, Degraded, or Rebuilding. Information Information provides the status of the RAID volume, for example, has a disk failed or not. Drive Count Drive Count provides the number of hard disk drives in the RAID volume. Chapter 3. Operating SAS/SATA MyStorage management software 21

Estimated Time Left This indicates the time left for the degraded RAID volume to be rebuilt. If the RAID volume is degraded, multiple fields change, as shown in the following illustration. 22 LSI Logic MyStorage Management Software: User s Guide for IBM SAS Controllers

RAID rebuilding If a RAID volume is broken, for example, one of the disks has failed and needs replacement, the RAID volume is automatically rebuilt, as shown in the following illustration. While rebuilding, the Information heading shows the progress of rebuilding. Chapter 3. Operating SAS/SATA MyStorage management software 23

RAID topology: storage devices This tab gives information about the types of storage devices in the RAID volume. There are two read only sub-tabs under each storage device. They are RAID drive information and RAID error information. RAID Drive Information RAID Drive Information This screen gives the basic information and status of a disk drive: OK, Failed, or Rebuilding. 24 LSI Logic MyStorage Management Software: User s Guide for IBM SAS Controllers

RAID Error Information SCSI smart errors are shown in the following illustration. Event logs The event log window traps and displays events as they take place in the SAS or RAID topology that is present in the system. It is also able to trace Discovery Errors. The event log panel has four attributes for pointing out an event: Severity, Server, Time, and Description. Severity This column shows the severity of the event. The severity is the extent to which a change in the topology effects the stability of the topology. Server This column indicates the server on which the event occurred. Time This column gives the time at which the event occurred. Description This column gives the description of the event. Chapter 3. Operating SAS/SATA MyStorage management software 25

The event panel can trace three types of events: SAS events, RAID events, and Discovery events. The following events are reported by the MyStorage management software. SAS events: v Loop detected v Unaddressable device found v Multiple ports with the same SAS address were detected v Expander error v SMP timeout v Expander route table out of entries v Route table index does not exist v SMP function failed v SMP CRC error v Multiple subtractives detected v Table-to-table detected v Multiple paths detected RAID events: v An integrated RAID volume created v An integrated RAID volume deleted v Volume settings changed v Volume status changed v Physical Disk field in a RAID volume configuration page changed v A new RAID physical disk page created v A RAID physical disk page deleted v Physical disk settings changed v Physical disk status changed v A new disk has been automatically added to an integrated RAID volume v SMART data has been received from an integrated RAID physical disk v The IOC processed a RAID action request message Discovery events: v A new target device was added v A device has stopped responding or is missing v SMART data has been received from a device v A new target device was added, but without a persistent Bus and TargetID mapping v An unsupported device was discovered 26 LSI Logic MyStorage Management Software: User s Guide for IBM SAS Controllers
