1.2 Terminology The document uses the following terms: RAID RAID is the abbreviation of “Redundant Array of Independent Disks”. There are different RAID levels with different degree of the data protection, data availability, performance to host environment. PD The Physical Disk belongs to the member disk of one specific volume group. VG Volume Group. A collection of removable media. One VG consists of a set of UDVs and owns one RAID level attribute. UDV User Data Volume.
WT Write-Through cache write policy. A caching technique in which the completion of a write request is not signaled until data is safely stored on non-volatile media. Each data is synchronized in both data cache and the accessed physical disks. WB Write-Back cache write policy. A caching technique in which the completion of a write request is signaled as soon as the data is in cache and actual writing to non-volatile media occurs at a later time.
iSCSI Internet Small Computer Systems Interface. CHAP Challenge Handshake Authentication Protocol. An optional security mechanism to control access to an iSCSI storage system over the iSCSI data ports. iSNS Internet Storage Name Service. 1.3 RAID levels RAID 0 Disk striping. RAID 0 needs at least one hard drive. RAID 1 Disk mirroring over two disks. RAID 1 needs at least two hard drives. N-way mirror Extension to RAID 1 level. It has N copies of the disk.

Chapter 4 Advanced operation 4.1 Rebuild If one physical disk of the VG which is set as protected RAID level (e.g.: RAID 3 , RAID 5, or RAID 6) is FAILED or has been unplugged/removed, then, the VG status is changed to degraded mode, the system will search/detect spare disk to rebuild the degraded VG to a complete one. It will detect dedicated spare disk as rebuild disk first, then global spare disk. i Series support Auto-Rebuild function.
When rebuilding, the status of PD/VG/UDV is “R”; and “R%” in UDV will display the ratio in percentage. After complete rebuilding, “R” and “DG” will disappear. VG will become complete one. Tips The list box doesn’t exist if there is no VG or only VG of RAID 0, JBOD. Because user cannot set dedicated spare disk for these RAID levels. Sometimes, rebuild is called recover; these two have the same meaning. The following table is the relationship between RAID levels and rebuild. RAID 0 Disk striping.
4.2 VG migration and expansion To migrate the RAID level, please follow the below procedures. If the VG migrates to the same RAID level of the original VG, it is expansion. 1. 2. Select “/ Volume config / Volume group”. Decide which VG to be migrated, click the button “ column next the RAID level. 3. Change the RAID level by clicking the down arrow mark “ ”. There will be a pup-up which shows if the HDD is not enough to 4. 5. 6.
Figure 4.2.3 (Figure 4.2.3: A RAID 0 migrates to RAID 5, complete percentage is 2%.) To do migration/expansion, the total size of VG must be larger or equal to the original VG. It does not allow expanding the same RAID level with the same hard disks of original VG. During setting migration, if user doesn’t setup correctly, controller will pop up warning messages. Below is the detail of messages. 1. 2. 3. 4. 5. 6. Invalid VG ID: Source VG is invalid. Degrade VG not allowed: Source VG is degraded.
4. Extension starts. If UDV needs initialization, it will display an “I” in “Status 3” and complete percentage of initialization in “R%”. Figure 4.3.1 (Figure 4.3.1: Extend UDV-R0 from 80GB to 90GB.) Tips The size of UDV extension must be larger than original. Caution UDV Extension cannot be executed during rebuild or migration. 4.4 Disk roaming Physical disks can be re-sequenced in the same system or move whole physical disks from system-1 to system-2. This is called disk roaming.
