Page 19: Introduction
1 Introduction With CentricStor, a virtual tape robot system is placed in front of the real tape robot system (with the real drives and cartridges). In this way the host and the real archive are fully decoupled. The virtual tape robot system knows what are referred to as virtual (logical) drives and virtual (logical) volumes.
Page 20: Objective And Target Group For The Manual
Objective and target group for the manual The host is connected using the following connection technologies: ESCON channels ● FibreChannel ● FICON ● Communication between the individual control units takes place via the LAN in CentricStor, the transport of the user data to and from the RAID system via the FibreChannel. The physical drives can be connected to the backend via both FibreChannel and SCSI technology.

Introduction Global Status The Global Status Monitor provides a graphical display of all important operating data in a window. XTCC The program XTCC is used mainly to monitor the individual CentricStor computers (ISPs) including the peripheral devices connected to the computers. Explanation of console messages This chapter describes the most important of the console messages.

Page 23: Centricstor - Virtual Tape Library
2 CentricStor - Virtual Tape Library 2.1 The CentricStor principle Conventional host robot system Host Figure 1: Conventional host robot system In a conventional real host robot system, the host system requests certain data cartridges to be mounted in a defined real tape drive. As soon as the storage peripherals (robots, drives) report that this has been completed successfully, data transfer can begin.
Page 24 The CentricStor principle Host robot system with CentricStor Host Figure 2: Host robot system with CentricStor With CentricStor, a virtual archive system is installed upstream of the real archive system with the physical drives and data cartridges. This enables the host to be completely isolated from the real archive.
Page 25 CentricStor - Virtual Tape Library As soon as a mount job is issued, the Library Manager checks whether the requested volume is already in the disk cache. If so, the volume is immediately released for processing by the application. If not, CentricStor requests the corresponding cartridge to be mounted onto a physical drive, and reads the logical volume into the disk cache.

CentricStor - Virtual Tape Library 2.2.1 ISP (Integrated Service Processor) CentricStor is a group of several processors, each running special software (UNIX derivative) as the operating system. These processors are referred to collectively as the ISP (Integrated Service Processor). Depending on the peripheral connection, the hardware configuration, the software configuration, and the task in the CentricStor system, a distinction is made between the following processor types: –...

Hardware architecture 2.2.1.2 ICP (Integrated Channel Processor) The ICP is the interface to the host systems connected in the overall system. Hosts BS2000/OSD, z/OS and OS/390 z/OS and OS/390 BS2000/OSD, Open Systems Figure 5: External and internal ICP connections Depending on the type of host system used, it is possible to equip an ICP with a maximum of 4 ESCON boards on the host side (connection with BS2000/OSD, z/OS or OS/390), with one or two FICON ports (connection with z/OS or OS/390), or with one or two FC boards (BS2000/OSD or open systems).

CentricStor - Virtual Tape Library 2.2.1.3 IDP (Integrated Device Processor) The IDP is the interface to the connected tape drives. CentricStor Figure 6: Internal and external IDP connections The IDP is responsible for communication with real tape drives. To optimize performance, only two real tape drives should be configured per IDP.
Page 30: Raid Systems For The Tape Volume Cache
Hardware architecture 2.2.2 RAID systems for the Tape Volume Cache A TVC (Tape Volume Cache) is the heart of the entire virtual archive system. It represents all of the Tape File Systems in which the logical volumes can be stored temporarily. One or more RAID systems (up to 8) are used for this.
Page 31: Fibrechannel (Fc)
CentricStor - Virtual Tape Library The metadata of the logical volumes to be written or read is stored on the 1st RAID system, as a result of which the usable capacity of this RAID system is reduced by 16 GB. A CentricStor can contain up to 8 RAID.
Page 32: Host Connection
Software architecture This SAN-based design means that each CentricStor component is in a position to access the TVC. 2.2.5 Host connection The host connection on the ICP is implemented using the following connection technologies: Host system Mainframe Open Systems FibreChannel with ESCON or FICON connections can be operated in mixed mode on an ICP.
Page 33 CentricStor - Virtual Tape Library MSP/XSP LIB/SP z/OS OS/390 HACC BS2000 ROBAR Open Systems ACSLS DAS-ACI SCSI Backup software Figure 8: Central role of the VLP in a CentricStor configuration VLP (Virtual Library Processor) The VLP is responsible for the coordination of the entire CentricStor system. Although the software can be activated on any of the ICP or IDP systems, it is recommended for perfor- mance reasons that you either provide a separate VLP, or activate the components of the VLP on one of the IDPs, since the CPU utilization is at its lowest here.
Page 34 Software architecture VLM (Virtual Library Manager) Each robot job from the requesting host system is registered in the VLM. To support the libraries, corresponding emulations (VLMF, VAMU, VACS, VDAS, VJUK) are used in CentricStor. The TVC is administered exclusively by the VLM. The VLM data maintenance contains the names of the logical volumes with which the TVC is to work.
Page 35: Operation
CentricStor - Virtual Tape Library 2.4 Operation CentricStor is operated via the graphical user interfaces GXCC (Global Extended Control Center) and XTCC (Extended Tape Control Center). These are used to perform all administration and configuration tasks. Using this control center, it is possible to display the current operating statuses of all CentricStor components, together with a large amount of performance and utilization data.

Administering the tape cartridges 2.5.2 Repeated writing of a logical volume onto tape If a logical volume which has already been saved onto tape is written to tape a second time following an update, the first backup will be declared invalid. The current volume is appended after the last volume of this tape or another tape with sufficient storage space.
Page 37: Reorganization Of The Tape Cartridges
CentricStor - Virtual Tape Library 2.5.4 Reorganization of the tape cartridges When a logical volume is released by the host’s volume management facility (e.g. MAREN in BS2000/OSD), it is flagged accordingly in the CentricStor data maintenance facility which contains the metadata for each volume. This process, combined with updates (see the section section “Creating a directory”...

Page 45: Snmp Support
CentricStor - Virtual Tape Library 2.8.3 SNMP support It is possible to integrate CentricStor into remote monitoring by an SNMP Management Station such as “CA Unicenter” or “Tivoli”. In the event of system errors (error weighting EMERGENCY, ALERT, ERROR, CRITICAL), CentricStor sends a trap to the SNMP Management Station, which causes the CentricStor icon to change color (insofar as this is supported by the SNMP Management Station).

Page 74: How Is A Physical Volume Reorganized
Reorganization 4. Physical volume inaccessible status The PLM can no longer access the physical volume. This can be due to the following reasons: – The robot cannot access the physical volume. – The tape header cannot be read. The logical volumes affected may need to be read in again from a backup copy (dual save) and backed up again.
Page 75: When Is A Reorganization Performed
Selected system administrator activities 4.4.3 When is a reorganization performed? Depending on the type of event or status which triggers reorganization, the PLM performs reorganization either immediately after the event occurs or within a configurable time of day interval. The following three events cause reorganization to be triggered immediately regardless of the time of day: Explicitly by means of a user command ●...
Page 76: Which Physical Volume Is Selected For Reorganization
Reorganization Once the number of scratch tapes reaches the hard limit again, the “all clear” is given (see page 76): SXPL011 ... PLM(#11): NOTICE: number of free PVs of PV-group <PVG> over absolute minimum (<num>) again For the following statuses, reorganization is only initiated within the configured time of day interval.
Page 77 Selected system administrator activities Only physical volumes in read status on which the relative proportion of valid data is less than the percentage value configured in the Fill Grade parameter are taken into account. If a physical volume is in write status and the percentage value for its valid data drops below the Fill Grade value, it is placed in read status and is therefore a candidate for reorganization.
Page 78: Own Physical Volumes For Reorganization Backup
Reorganization 4.4.5 Own physical volumes for reorganization backup The PLM distinguishes between backup requests from the host and backup requests which are caused by a reorganization. As long as the number of scratch tapes is above the hard minimum, the PLM attempts to use a physical volume exclusively for the request type invol- ved.
Page 79: Configuration Parameters
Selected system administrator activities 4.4.7 Configuration parameters All configuration parameters can be set specifically for each physical volume group. It must be ensured that a dependency on the number of available drives exists and that not too many reorganizations take place in parallel, otherwise these will be delayed unneces- sarily on account of the lack of drives.
Page 80 Reorganization When the percentage of valid data on a physical volume which is in write status and is not currently mounted in a Physical Device Service is below this limit value and at the same time a reorganization is in progress because a scratch tape limit value has been fallen below, this physical volume is placed in read status, and it is therefore a candidate for reorganization.

Selected system administrator activities PLM Refresh Interval Number of days after which the physical volumes in this group are to be recopied. The count starts with the day on which the physical volume switched from scratch status to write status. This value must be defined in accordance with the recommendations of the tape manufacturer.

Page 86 Technical design In this configuration GXCC runs on the remote computer (e.g. Windows PC) and uses the interfaces of its user interface directly. At short intervals GXCC inquires of the CentricStor VLP whether there is new data. Here only 20 bytes are transferred. If new data is available, the VLP sends the GXCC user data to the remote computer, which edits the data and forwards it to the output screen.

Page 326 General CentricStor recognizes various ISP types. Integrated Channel Processor An ICP has a permanent connection to one or more BS2000/OSD, z/OS or OS/390 hosts via ESCON/FICON adapters or to an open systems host via an FC controller operating as a host connection. Host adapters and virtual devices are available only on ICPs.
Page 327 XTCC In the case of an ICP_IDP combination, the display is somewhat different: PDSs and emulations/virtual devices are located on the same level in the diagram. The PDSs are connected to the associated device controller, and the emulations are connected to the associated host adapter(s).

Page 562: Transferring Volumes
Transferring volumes 12.3 Transferring volumes 12.3.1 Introduction A transfer enables LVs to be exported from a CentricStor system and imported into another CentricStor. For the export these LVs are temporarily copied into the special LV group TR-LVG using “plmcmd trans …” commands and saved on PVs of the special PV group TR-PVG. These PVs can then be removed and transported to another CentricStor.
Page 563: Export Procedure
Appendix 12.3.2 Export procedure 1. Copying LVs TR-LVG A00001 Z10000 TR-PVG A00001 Z10000 Figure 36: Copying an LV to TR-PVG With the aid of the transfer-out command (see the the PLM creates an additional copy of the LVs selected for export in a special transfer LVG, theTR-LVG.
Page 564: Import Procedure
Transferring volumes The transfer volume groups TR-LVG and TR-PVG are now ready for another transfer. 3. Removing PVs from a library The PVs determined above can now be physically removed from the library using a DAS or ACSLS command (see the The existing copies of these LVs on other PVs when Mono Save or Dual Save is used remain unaffected by the transfer: These copies are retained in the physical library unchanged.

Page 569 Appendix If the VLM does not know the LV, no restore command is issued to the PLM for the purpose of actually reading in the LV. The PLM therefore waits for an unlimited time, and no progress can be recognized when you query the jobs (plmif query -j -G TR-PVG). You can then either create this LV in the LVG, or skip this LV using the transfer-in cancel command (see the Options...
