PAGE 292
VTrak E-Class Product Manual RAID 0 – Stripe When a logical drive is striped, the read and write blocks of data are interleaved between the sectors of multiple physical drives. Performance is increased, since the workload is balanced between drives or “members” that form the logical drive. Identical drives are recommended for performance as well as data storage efficiency. Figure 1.
PAGE 293
Chapter 7: Technology Background RAID 1 – Mirror When a logical drive is mirrored, identical data is written to a pair of physical drives, while reads are performed in parallel. The reads are performed using elevator seek and load balancing techniques where the workload is distributed in the most efficient manner. Whichever drive is not busy and is positioned closer to the data will be accessed first.
PAGE 294
VTrak E-Class Product Manual RAID 1E – Enhanced Mirror RAID 1E offers the security of mirrored data provided by RAID 1 plus the added capacity of more than two physical drives. It also offers overall increased read/ write performance plus the flexibility of using an odd number of physical drives. With RAID 1E, each data stripe is mirrored onto two physical drives. If one drive fails or has errors, the other drives continue to function, providing fault tolerance. Figure 3.
PAGE 295
Chapter 7: Technology Background RAID 5 – Block and Parity Stripe RAID 5 organizes block data and parity data across the physical drives. Generally, RAID Level 5 tends to exhibit lower random write performance due to the heavy workload of parity recalculation for each I/O. RAID 5 is generally considered to be the most versatile RAID level. It works well for file, database, application and web servers. Figure 4.
PAGE 296
VTrak E-Class Product Manual RAID 6 – Block and Double Parity Stripe RAID level 6 stores dual parity data is rotated across the physical drives along with the block data. A RAID 6 logical drive can continue to accept I/O requests when any two physical drives fail. Figure 5. RAID 6 stripes all drives with data and dual parity Double Distributed (Wide-space Q+Q) Parity Data Blocks Physical Drives Hence, a RAID 6 logical drive with (7) 100 GB physical drives will have a capacity of 500 GB.
PAGE 297
Chapter 7: Technology Background RAID 10 – Mirror + Stripe Mirror + Stripe combines both of the RAID 1 and RAID 0 logical drive types. RAID 10 can increase performance by reading and writing data in parallel— striping—while protecting data by duplicating it—mirroring. Promise implements RAID 10 by creating a data stripe over one pair of disk drives, then mirroring the stripe over a second pair of disk drives. Some applications refer to this method as RAID 0+1. Figure 6.
PAGE 298
VTrak E-Class Product Manual RAID 50 – Striping of Distributed Parity RAID 50 combines both RAID 5 and RAID 0 features. Data is striped across physical drives as in RAID 0, and it uses distributed parity as in RAID 5. RAID 50 provides data reliability, good overall performance, and supports larger volume sizes. Figure 7.
PAGE 299
Chapter 7: Technology Background RAID 50 Axles When you create a RAID 50, you must specify the number of axles. An axle refers to a single RAID 5 logical drive that is striped with other RAID 5 logical drives to make RAID 50. An axle can have from 3 to 32 physical drives, depending on the number of physical drives in the logical drive. The chart below shows RAID 50 logical drives with 6 to 16 physical drives, the available number of axles, and the resulting distribution of physical drives on each axle.
PAGE 300
VTrak E-Class Product Manual RAID 60 – Striping of Double Parity RAID 60 combines both RAID 6 and RAID 0 features. Data is striped across disks as in RAID 0, and it uses double distributed parity as in RAID 6. RAID 60 provides data reliability, good overall performance and supports larger volume sizes. Figure 8. RAID 60 is a combination of RAID 6 and RAID 0 Double Distributed Parity Axle 1 Data Stripes Axle 2 Disk Drives Figure 9.

PAGE 305
Chapter 7: Technology Background Choosing Stripe Size Stripe Size, also called “Stripe Block Size”, refers to the size of the data blocks written to, and read from, the physical drives. Stripe Size is specified when you create a disk array. In order to change the Stripe Size of an existing disk array, you must delete the disk array and create a new one. You can choose Stripe Size directly when you use the Advanced function to create a disk array.
PAGE 306
VTrak E-Class Product Manual • Linux operating systems with the 2.4 kernel do not support variable sector sizes. For these OSes, always choose the default 512 B sector size. • Linux operating systems with the 2.6 kernel support 64-bit LBA. For these OSes, always choose the default 512 B sector size.
PAGE 307
Chapter 7: Technology Background Read Cache Policy • Read Cache – The read cache is enabled. • Read Ahead – The read cache and the read-ahead feature are enabled. Read-ahead anticipates the next read and performs it before the request is made. Can increase read performance. • No Cache – The read cache is disabled. Write Cache Policy • Write Back – Data is written first to the cache, then to the logical drive. Better performance.
PAGE 308
VTrak E-Class Product Manual The write policy automatically changes to Write Thru. When the battery comes back online, the write policy automatically changes back to Write Back. To enable the Adaptive Writeback Cache option, see “Making Controller Settings” on page 122 or page 177. Also see “Replacing a Cache Battery” on page 265. Host Cache Flushing When host cache flushing is enabled, the VTrak immediately flushes the data in its controller cache to the drives when the Host sends a Flush Cache command.
PAGE 309
Chapter 7: Technology Background • Set Redundancy Type to Active-Active. See “Setting Redundancy for the Subsystem” on page 64 or page 172 • Enable Cache Mirroring under subsystem settings. See “Setting Redundancy for the Subsystem” on page 64 or page 172 • On subsystems with two controllers, when Cache Mirroring is disabled, LUN Affinity is enabled automatically.
PAGE 310
VTrak E-Class Product Manual Automatic is the default and preferred setting because it will balance the logical drive assignments for you. When you create a logical drive using the Automatic or Express disk array creation, the logical drives are assigned alternatively between Controllers 1 and 2 automatically.
PAGE 311
Chapter 7: Technology Background Capacity Coercion This feature is designed for fault-tolerant logical drives (RAID 1, 1E, 5, 10, 50, and 60). It is generally recommended to use physical drives of the same size in your disk arrays. When this is not possible, physical drives of different sizes will work but the system must adjust for the size differences by reducing or coercing the capacity of the larger drives to match the smaller ones.
PAGE 312
VTrak E-Class Product Manual Hot Spare Drive(s) A hot spare is a disk drive that is connected to the disk array system but is not assigned as a member of the disk array. In the event of the failure of a drive within a functioning fault tolerant disk array, the hot spare is activated as a member of the disk array to replace a drive that has failed. VTrak will replace a failing disk drive in a disk array with an unassigned drive, if one is available. The unassigned drive is not part of any disk array.
PAGE 313
Chapter 7: Technology Background is done, your disk array will have a different RAID level and/or a larger capacity. See “Migrating a Disk Array” on page 148 or page 196. In most cases, you must add one or more physical drives during the migration process. You can never reduce the number of physical drives. The tables below show the migration options for a source logical drive according to its RAID level. The available target RAID levels are shown with their requirements.
PAGE 314
VTrak E-Class Product Manual RAID 1 A RAID 1 Source logical drive can migrate to the following Target logical drives: Target Requirements RAID 0 None. RAID 1E 3 or more physical drives. Add 1 or more physical drives. RAID 5 3 physical drives minimum, 32 maximum. RAID 1 must have less than 32 physical drives. Add 1 or more physical drives. RAID 10 4 physical drives minimum. Even number of physical drives. Add 2 or more physical drives. RAID 50 6 physical drives minimum, 32 per axle maximum.
PAGE 315
Chapter 7: Technology Background RAID 5 A RAID 5 Source logical drive can migrate to the following Target logical drives: Target Requirements RAID 0 None. RAID 1E None. RAID 5 Add physical drives. 32 maximum. RAID 6 4 physical drives minimum, 32 maximum. If existing physical drives have no unused space, add 1 or more physical drives. RAID 10 4 physical drives minimum. Even number of physical drives. If existing physical drives have no unused space, add 1 or more physical drives.
PAGE 316
VTrak E-Class Product Manual RAID 10 A RAID 10 Source logical drive can migrate to the following Target logical drives: Target Requirements RAID 0 None. RAID 1E None. RAID 5 3 physical drives minimum, 32 maximum. RAID 10 must have less than 16 physical drives. RAID 6 4 physical drives minimum, 32 maximum. RAID 10 must have less than 32 physical drives. If existing physical drives have no unused space, add 1 or more physical drives. RAID 10 Add physical drives. Even number of physical drives.
PAGE 317
Chapter 7: Technology Background RAID 50 A RAID 50 Source logical drive can migrate to the following Target logical drives: Target Requirements RAID 0 None. RAID 1E None. RAID 5 32 physical drives maximum. RAID 50 must have less than 32 physical drives. RAID 6 32 physical drives maximum. RAID 50 must have less than 32 physical drives. If existing physical drives have no unused space, add 1 or more physical drives. RAID 10 Even number of physical drives. RAID 50 Add physical drives.
PAGE 318
VTrak E-Class Product Manual Important • The Target disk array may require more physical drives than the Source disk array • If the Target disk array requires an EVEN number of physical drives but the Source disk array has an ODD number, ADD a physical drive as part of the migration process • You cannot reduce the number of physical drives in your disk array, even if the Target disk array requires fewer physical drives than the Source disk array • RAID 1 (mirroring) works with two drives only.

Chapter 7: Technology Background Current LD Size Maximum LD Expansion Size 8 to 16 TB 16 TB 4096 bytes 4 to 8 TB 8 TB 2048 bytes 2 to 4 TB 4 TB 1024 bytes up to 2 TB 2 TB 512 bytes Sector Size At this point, you have the choice of: • Format the unpartitioned/unformatted capacity as a second logical drive • Delete the existing disk array and create a new one in the desired size Delete and Recreate If you require a logical drive larger than the maximum expansion size: 1.
PAGE 320
VTrak E-Class Product Manual Predictive Data Migration (PDM) Predictive Data Migration (PDM) is the migration of data from the suspect disk drive to a spare disk drive, similar to Rebuilding a Logical Drive. But unlike Rebuilding, PDM constantly monitors your disk drives and automatically copies your data to a spare disk drive before the disk drive fails and your Logical Drive goes Critical. PDM is triggered automatically, based on Background Activity Settings.
PAGE 321
Chapter 7: Technology Background Transition The Transition feature enables you to specify “permanent” spare drives for your VTrak subsystem. Transition is the process of replacing a revertible spare drive that is currently part of a disk array with an unconfigured physical drive or a nonrevertible spare. The revertible spare drive returns to its original status. Transition happens automatically when the following sequence of events takes place: • You create a revertible spare drive.
PAGE 322
VTrak E-Class Product Manual In the example above, there is a four-drive RAID 5 disk array and a global spare drive. Physical drives 1, 2, 3, and 4 belong to the disk array. Physical drive 5 remains unconfigured. Physical drive 6 is a revertible spare drive. If a physical drive fails in a disk array and there is a spare drive of adequate capacity available, the controller automatically rebuilds the array using the spare drive.
PAGE 323
Chapter 7: Technology Background Automatic Transition At this juncture, you would replace the failed drive in slot 3 with a new one of the same or greater capacity. When the VTrak controller detects the new drive in slot 3, it will: • Automatically transition the data on drive 6 to drive 3 • Return drive 6 to spare status When the Automatic Transition is finished, physical drives 1, 2, 3, and 4 belong to the disk array and physical drive 6 is a revertible spare drive.

Chapter 8: Troubleshooting Critical & Offline Disk Arrays A fault-tolerant disk array—RAID 1, 1E, 5, 10, and 50—goes critical when a disk drive is removed or fails. A RAID 6 or 60 disk array—goes degraded when a disk drive is removed or fails and critical when two disk drives are removed of fail. Due to the fault tolerance of the disk array, the data is still available and online.
PAGE 358
VTrak E-Class Product Manual After the disk array rebuilds itself using the spare drive, you must replace the failed drive. To set up a spare drive, see “Creating a Spare Drive” on page 161 (WebPAM PROe) or page 201 (CLU). Without a Hot Spare Drive If there is no hot spare drive of adequate capacity, you must remove the failed drive and install an unconfigured replacement drive of the same or greater capacity in the same slot as the failed drive.
PAGE 359
Chapter 8: Troubleshooting Figure 15.Drive carrier LEDs Status Activity During rebuilding, you can still read and write data to the logical drive. However, fault tolerance is lost until the Disk Array returns to OK (not-rebuilding) status.
PAGE 360
VTrak E-Class Product Manual Incomplete Array An incomplete array can result from any of the following conditions: • The NVRAM watermark for the RAID level migration currently in progress is missing or cannot be found • A physical drive goes missing during transport See “Physical Drive Failed” on page 343 for more information.
PAGE 361
Chapter 8: Troubleshooting Physical Drive Problems Physical Drive Offline Check the drive for: • PFA Condition – Caused by a bad block or sector. See “Clearing Stale and PFA Conditions” on page 135 or page 187. • Stale Configuration – Caused by obsolete array information on the physical drive. Identify the disk array to which the physical drive belongs. Then delete the disk array. See “Deleting a Disk Array” on page 145 or page 193.
PAGE 362
VTrak E-Class Product Manual Because the setting for migration under NVRAM requires special access, most users will not encounter this condition. Physical Drive Fails during Transport Transport is the action of moving the physical drives of a disk array: • To different slots in the same VTrak enclosure • From one VTrak enclosure to another If a physical drive fails during a transport, or you do not move all of the physical drives to their new locations, WebPAM PROe will display an incomplete array.

The Enclosure screen displays. See Figure 16. Figure 16.Enclosure information in Management View In this example, a power supply has failed. The Enclosure Diagram displays color and motion changes to identify the failed power supply. In this case, you must replace the power supply.
PAGE 364
VTrak E-Class Product Manual Overheating Overheating is a potentially serious condition because the excessively high temperatures can lead to disk drive failure and controller malfunction. Overheating usually results from: • Fan failure • Poor air circulation around the enclosure WebPAM PROe reports failed fans along with elevated temperature. On VTrak, there are two kinds of fans: • Power supply • Cooling unit If a power supply fan fails, you must replace the power supply.
PAGE 365
Chapter 8: Troubleshooting Power Supplies VTrak subsystems are equipped with redundant power supplies. The advantage of dual power supplies is that, should one fail, the other will continue powering the subsystem until the faulty one can be replaced. The subsystem is capable of operating on a single power supply. As a result, if one power supply fails you must watch the front panel LEDs or WebPAM PROe in order to become aware of the condition.

Chapter 9: Support What happens if a logical drive goes critical? On the front of VTrak, the logical drive LED turns amber and the buzzer sounds (if enabled). See “Critical & Offline Disk Arrays” on page 339. VTrak’s Netsend service does not report all events to Windows PCs. This condition results from a shortcoming in Windows Messenger that causes miscommunication with Netsend. Promise is developing a workaround at the time of this writing. Note that all events are correctly reported in the Event Viewer.

VTrak E-Class Product Manual Task 1: Meeting Package Requirements The latest device mapper and multipath packages must be loaded onto your Linux host before configuring Device Mapper Multipath (DM-MP). When this document was written, the current versions were: • • • • • • • • • • For RHEL 5 • device-mapper-1.02.13-1.el5 • device-mapper-multipath-0.4.7-8.el5 For RHEL 5.1 • device-mapper-1.02.20-1.el5 • device-mapper-multipath-0.4.7-12.el5 For RHEL 5.2 • device-mapper-1.02.24-1.
PAGE 413
Appendix C: Multipathing on Linux Installing Packages The easiest and most effective way to install the device mapper and multipath tool is during OS installation. The device mapper installs by default, regardless of the configuration you select. However, you must manually specify the multipath tool, as it does not install as a part of any of the configurations of either OS. The multipath tool is listed as an option under Base System.
