VTrak E-Class Product Manual Replacing a RAID Controller The RAID Controller monitors and manages the logical drives. When this controller is replaced, all of your logical drive data and configurations remain intact because this logical drive information is stored on the disk drives. Caution The RAID controller is NOT hot-swappable if your VTrak has only one controller. Power-down the VTrak before removing it. If your VTrak has two RAID controllers, you can hot-swap one controller at a time.
Chapter 6: Maintenance Single Controller Subsystem Removing the old controller To remove the RAID Controller on a single-controller subsystem: 1. Shutdown the VTrak. See “Shutting Down the Subsystem” on page 103 (WebPAM PROe) or page 209 (CLU). 2. Switch off the power. 3. Disconnect the Fibre Channel or SAS cables, management, serial and power cables. 4. On the controller handle, press the release button and pull the handle downward. See Figure 21. 5.

Chapter 7: Technology Background This chapter covers the following topics: • Introduction to RAID (below) • Choosing a RAID Level (page 242) • Choosing Stripe Size (page 245) • Choosing Sector Size (page 245) • Cache Policy (page 246) • Cache Mirroring (page 248) • LUN Affinity (page 249) • Capacity Coercion (page 250) • Initialization (page 251) • Hot Spare Drive(s) (page 251) • Partition and Format the Logical Drive (page 252) • RAID Level Migration (page 252) • Media Patrol (page
VTrak E-Class Product Manual RAID 0 – Stripe When a disk array is striped, the read and write blocks of data are interleaved between the sectors of multiple drives. Performance is increased, since the workload is balanced between drives or “members” that form the disk array. Identical disk drives are recommended for performance as well as data storage efficiency. The disk array’s data capacity is equal to the number of disk drive members multiplied by the smallest drive's capacity.
Chapter 7: Technology Background RAID 1 – Mirror When a disk array is mirrored, identical data is written to a pair of 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. With RAID 1, if one drive fails or has errors, the other mirrored drive continues to function.
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 disk drives. It also offers overall increased read/write performance plus the flexibility of using an odd number of disk drives. With RAID 1E, each data stripe is mirrored onto two disk drives. If one drive fails or has errors, the other drives continue to function, providing fault tolerance.
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 Distributed Parity Data Blocks Disk Drives Figure 3.
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 disk array can continue to accept I/O requests when any two physical drives fail. Double Distributed (Wide-space Q+Q) Parity Data Blocks physical drives The total capacity of a RAID 6 disk array is the smallest physical drive times the number of physical drives, minus two.
Chapter 7: Technology Background RAID 10 – Mirror + Stripe Mirroring/striping combines both of the previous RAID 1 and RAID 0 disk array types. RAID 10 is similar though not identical to RAID 0+1. RAID 10 can increase performance by reading and writing data in parallel while protecting data with duplication. At least four drives are needed for RAID 10 to be installed. With four disk drives, the drive pairs are striped together with one pair mirroring the first pair.
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 disks 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. Distributed Parity Axle 1 Data Stripes Axle 2 Disk Drives Figure 5.
Chapter 7: Technology Background The chart below shows RAID 50 arrays with 6 to 16 physical drives, the available number of axles, and the resulting distribution of physical drives on each axle. RAID 50 Array No. of Drives No.
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.

VTrak E-Class Product Manual Choosing a RAID Level There are several issues to consider when choosing the RAID Level for your VTrak disk array. The following discussion summarizes some advantages, disadvantages, and applications for each choice.
Chapter 7: Technology Background RAID 1E Advantages Disadvantages Implemented as a mirrored disk array whose segments are RAID 0 disk arrays High I/O rates are achieved thanks to multiple stripe segments Can use an odd number of disks Very high disk overhead - uses only 50% of total capacity Recommended Applications for RAID 1E • Imaging applications • Database servers • General fileserver RAID 5 Advantages Disadvantages High Read data transaction rate Medium Write data transaction rate Good ag
VTrak E-Class Product Manual RAID 10 Advantages Disadvantages Implemented as a mirrored disk array whose segments are RAID 0 disk arrays High I/O rates are achieved thanks to multiple stripe segments Very high disk overhead - uses only 50% of total capacity Recommended Applications for RAID 10 • Imaging applications • Database servers • General fileserver RAID 50 Advantages Disadvantages High Read data transaction rate Medium Write data transaction rate Good aggregate transfer rate High reliabi
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 select Stripe Size directly when you use the Advanced function to create a disk array.
VTrak E-Class Product Manual • Linux operating systems with the 2.6 kernel support 64-bit LBA. For these OSes, always choose the default 512 B sector size. 2 TB Limitation If your Host PC runs Windows 2000 or Windows XP (32-bit), and you want to create logical drives larger than 2TB, you must choose a sector size larger than 512 B when you create the logical drive. The table below correlates sector size with logical drive capacity.
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.
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 107 or page 156. Also see “Replacing a Cache Battery” on page 224. Cache Mirroring VTrak subsystems with two controllers include a Cache Mirroring feature.
Chapter 7: Technology Background • If Controller 1 goes offline, Controller 2 takes over access to the logical drives assigned to Controller 1. • All write data that is still in the controller cache will be written to the logical drives, even though the controller managing them has failed. • If Controller 1 comes back online, Controller 1 takes back access to the logical drives assigned to it.
VTrak E-Class Product Manual Logical Drive Settings After you have created a logical drive, you can click on the Settings tab and manually change the Preferred Controller ID between Controller 1 and Controller 2. See “Making Logical Drive Settings” on page 136. If you create logical drives with LUN Affinity disabled, the Preferred Controller ID will show N/A, and your logical drives will be visible to both controllers.
Chapter 7: Technology Background • GB Truncate – (Default) Reduces the useful capacity to the nearest 1,000,000,000 byte boundary. • 10GB Truncate – Reduces the useful capacity to the nearest 10,000,000,000 byte boundary. • Group Rounding – Uses an algorithm to determine how much to truncate. Results in the maximum amount of usable drive capacity. • Table Rounding – Applies a predefined table to determine how much to truncate. Capacity Coercion also affects a replacement drive used in a disk array.
VTrak E-Class Product Manual • Dedicated – An unassigned disk drive that can only be used by a specified disk array. The hot spare policy function lets you select whether a disk array will access any unassigned disk drive or a designated drive in the event of disk drive failure. See “Managing Spare Drives” on page 141 (WebPAM PROe) or page 190 (CLU) for information on how to make this setting.
Chapter 7: Technology Background Different types of disk arrays use different organizational models and have varying benefits. The following outline breaks down the properties for each type of RAID supported by Promise products.
VTrak E-Class Product Manual Important • The Target disk array may require more disk drives than the Source disk array • If the Target disk array requires an EVEN number of disk drives but the Source disk array has an ODD number, ADD a disk drive as part of the migration process • You cannot reduce the number of disk drives in your disk array, even if the Target disk array requires fewer disk 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. 2.
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. See “Running PDM” on page 68 for WebPAM PROe or page 173 for the CLU.
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.
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.
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.
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 142 (WebPAM PROe) or page 190 (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.
Chapter 8: Troubleshooting Figure 13.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.
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 293 for more information.
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 119. • 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 125. If the error condition remains on the physical drive, clear the error condition.
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.
Chapter 8: Troubleshooting Enclosure Problems WebPAM PROe displays yellow !s components that need attention. red Xs in Tree View to identify When a yellow ! appears over a Subsystem in Tree View, click on the Enclosure icon. The Enclosure screen will display (below). Figure 14.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.
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.
Chapter 8: Troubleshooting Power Supplies VTraks 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. VTrak 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.
