2.7 iSCSI introduction iSCSI (Internet SCSI) is a protocol which encapsulates SCSI (Small Computer System Interface) commands and data in TCP/IP packets for linking storage devices with servers over common IP infrastructures. iSCSI provides high performance SANs over standard IP networks like LAN, WAN or the Internet. IP SANs are true SANs (Storage Area Networks) which allow few of servers to attach to an infinite number of storage volumes by using iSCSI over TCP/IP networks.
The host side needs an iSCSI initiator. The initiator is a driver which handles the SCSI traffic over iSCSI. The initiator can be software or hardware (HBA). Please refer to the certification list of iSCSI HBA(s) in Appendix A. OS native initiators or other software initiators use the standard TCP/IP stack and Ethernet hardware, while iSCSI HBA(s) use their own iSCSI and TCP/IP stacks on board. Hardware iSCSI HBA(s) would provide its initiator tool. Please refer to the vendors’ HBA user manual.
browser and type the DHCP address: (The DHCP address is dynamic and user may need to check every time after reboot again.) When DHCP service is not available, IS16GL use zero config (Zeroconf) to get an IP address. E.g., on LCM. IS16GL gets a DHCP address 192.168.10.50 from DHCP server. 192.168.10.50 IS16GL ← http://192.168.10.50 or https://192.168.10.50 (https: connection with encrypted Secure Sockets Layer (SSL). Please be aware of the https function is slower than http.
Default password: 00000000 Tips SB-3164-G1A3 Series only support SSH for remote control. For using SSH, the IP address and the password is required for login. 2.9 Enclosure 2.9.1 LCM There are four buttons to control IS16GL LCM (LCD Control Module), including: (Escape), and (Enter). • (up), ‚ (down), After booting up the system, the following screen shows management port IP and model name: 192.168.10.

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. IS16GL 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.
RAID 50 Striping over the member RAID 5 volumes. RAID 50 allows two hard drives fails or unplugging, but at different arrays. RAID 60 Striping over the member RAID 6 volumes. RAID 40 allows four hard drives fails or unplugging, but each two at different arrays. JBOD The abbreviation of “Just a Bunch Of Disks”. No protection of data. VG fails if any hard drive fails or unplugs. 4.2 VG migration and expansion To migrate the RAID level, please follow the below procedures.
Figure 4.2.1 Figure 4.2.2 (Figure 4.2.2: A RAID 0 with 2 physical disks migrates to RAID 5 with 3 physical disks.) Figure 4.2.3 (Figure 4.2.3: A RAID 0 migrates to RAID 5, complete percentage is 12%.
Tips 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. "Invalid VG ID": Source VG is invalid. "Degrade VG not allowed": Source VG is degraded. "Initializing/rebuilding operation's going": Source VG is initializing or rebuilding.
Figure 4.3.1 Figure 4.3.2 (Figure 4.3.2: Extend UDV-R0 from 5GB to 10GB.) Tips The size of UDV extension must be larger than original. Caution UDV Extension cannot be executed during rebuild or migration. 4.4 Snapshot /Rollback IS16GL Snapshot-on-the-box captures the instant state of data in the target volume in a logical sense. The underlying logic is Copy-on-Write -- moving out the to-be-written data to certain location whenever a write action occurs since the time of data capture.
unfortunate reason it might be (e.g. virus attack, data corruption, human errors and so on). Snap UDV is allocated within the same VG in which the snapshot is taken, we suggest to reserve 20% of VG size or more for snapshot space. Please refer to Figure 4.4.1 for snapshot concept. Figure 4.4.1 Caution Snapshot /rollback features need 512MB RAM at least. Please also refer to RAM certification list in Appendix A. 4.4.1 Create snapshot volume To take a snapshot of the data, please follow the procedures.
4. 5. 6. 7. These numbers mean “Free snapshot space” and “Total snapshot space”. Choose a UDV by clicking the checkbox of the row and then click “ ”. A snapshot UDV is created with the date and time taken snapshot of the chosen UDV. The snapshot UDV size is the same as the chosen UDV no matter the actual snapshot UDV data occupies. Attach LUN to UDV, please refer to section 3.6.6 Logical unit number for more detail. Done. It can be used as a disk. Figure 4.4.1.1 (Figure 4.4.1.1: No.1 is a RAID 0 UDV.
4.4.2 Auto snapshot The snapshot copies can be taken manually or by schedule such as hourly or daily. Please follow the procedures. 1. 2. 3. 4. 5. Select “/ Volume config / User data volume”. Create a snapshot space. Please refer to section 4.4.1 for more detail. ” in “Snapshot (GB)” column to set auto snapshot . Click “ The auto snapshot can be set at the period of monthly, weekly, daily, or hourly. Done. It will take snapshots automatically. Figure 4.4.2.1 (Figure 4.4.2.
4.4.3 Rollback The data in snapshot UDV can rollback to original UDV. Please follow the procedures. 1. 2. 3. Select “/ Volume config / User data volume”. Take one or more snapshots. Please refer to section 4.4.1 for more detail. ” in “Snapshot (GB)” column to rollback the data, which Click “ user can recover data to the time that snapshot is taken. Rollback function has some constraints as described in the following: 1. 2. 3. 4. Minimum RAM size of enabling rollback function is 512MB.
capacity needs to be greater or equal to the source capacity. (The target UDV capacity is equal or larger than the source UDV capacity.) To do a QCopy task, please follow the below steps: 1. 2. 3. 4. 5. 6. 7. 8. 9. Take snapshot on the source UDV, for detail setup steps of snapshot, please refer to section 4.4.1. When setup UDV block size, please set 512B for the block size. The QCopy now supports 512B block size only.
Figure 4.5.1 (Figure 4.5.1: setup QCopy on selected snapshot UDV) Figure 4.5.2 (Figure 4.5.2: input the target system data port IP address) Figure 4.5.3 (Figure 4.5.3: select the target UDV LUN, the target UDV capacity must be equal or larger than the source UDV capacity.) Figure 4.5.4 (Figure 4.5.4: click OK after the target UDV is dismounted from host/server.) Figure 4.5.5 (Figure 4.5.
Caution Before executing QCopy, it is better to dismount target file system for avoiding any inconsistent data IO. SB-3164-G1A3 controller also send pop-up message when user checks QCopy function.
4.6 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. Disk roaming has some constraints as described in the following: 1. 2. Check the firmware of two systems first. It’s better that both have same firmware version or newer. Whole physical disks of related VG should be moved from system-1 to system-2 together.

Figure G.9 H. Installation Steps for Large Volume (TB) Introduction: IS16GL are capable to support large volumes (>2TB) on all product lines. When connecting IS16GL to 64bit OS installed host/server, the host/server is inherently capable for large volumes from the 64bit address.
7. 8. 9. Gigabit LAN switches. (Recommended) or Gigabit LAN switches with VLAN/LACP/Trunking functions. (Optional) CHAP security information, including CHAP usernames and secrets. (Optional) Setup the hardware connection before power up servers and IS16GL. Connect console cable, management port cable, SCSI cables, terminators, and iSCSI data port cables first. Step A: configure your target 1. Go to \Volume config\Volume group, create a VG. Figure H.1: create VG. Figure H.2: choose RAID level and disks.
Figure H.4: a RAID 6 (size 2793G) VG is created. 2. Go to \Volume config\User data volume, create a UDV Figure H.5: create UDV. Figure H.6: setup capacity, stripe height, and block size for UDV. Notice: When the OS is 64bit, user can set the block size to any available value. If the OS is 32bit, user has to change the block size to larger values than 512B. There will be a confirmation pop-up when UDV size is over 2TB for reminding. Figure H.
