iso file you have downloaded earlier and this would be self-explanatory to install a VM in Virtual Box. Post above step, build / install SLES with the. Once VirtualBox is installed, and before you deploy VM’s, create a “VirtualBox Host-Only Ethernet Adapter” as below,Ĭhoose “Configure Adapter Manually” and disable DHCP Server in the other TAB.Ĭreate multiple adapters if you wish to configure “bond” networks (combining 2 or more interfaces to avoid single point of failures).īond0 (Just a name like eth0, and nothing to confuse) – As an example, here I have created bond0 combing eth1 and eth4 from yast2 (yast2 – GUI for SLES configuration and settings) but for this lab I have not used bonding of network interfaces and below screen is just for an understanding. NOTE: Steps – Installation of virtual box, SLES on VirtualBox, TrueNAS installation on VirtualBox are self-explanatory as much content is already available over web.

Create SBD in TrueNAS VM and mount that to SLES VM’S.Clone above created VM to construct 2 nd VM.

Configure Network before you install VM’s.NOTE: For lab setup I have used minimum configuration and based on RTO these has to be adjusted eliminating all the single point of failures. True NAS – (to provision SBD, NFS (basically shared storage)) Hostname: nasvm (TrueNAS) (VM3) – to create iSCSI device and NFS shares.Hostname: noadea (SLES15) (VM1), Hostname: nobeb (SLES15) (VM2) – to host resources.So, its reachable even if one 1 VM fails. Good overview of managing ANY – 1 resource (Be it, HANA DB, ASCS, SCS, etc.,) will clarify our understanding in managing any kind of resource.Ī special Thanks to Mayne for explaining the concepts so well ! In reference to Open SAP course (Say Goodbye to Downtime with SUSE Linux Enterprise Server ), following lab environment was setup and could be useful for someone who wish to create everything from scratch. In RHEL 7, all storage fabrics are managed with the targetcli utility.Configuring HA for a resource (Resource can be IP, DB, Webserver, etc.,) In addition to iSCSI, LIO supports a number of storage fabrics including Fibre Channel over Ethernet (FCoE), iSCSI access over Mellanox InfiniBand networks (iSER), and SCSI access over Mellanox InfiniBand networks (SRP). RHEL/CentOS 7 uses the Linux-IO (LIO) kernel target subsystem for iSCSI. iSCSI uses the existing IP infrastructure and does not require any additional cabling, as is the case with Fibre Channel (FC) storage area networks. To the client systems, the storage devices appear to be locally attached. Client systems (initiators) access the remote storage devices over IP networks. Storage devices are attached to servers (targets). iSCSI provides shared storage among a number of client systems. iSCSI uses IP networks to encapsulate SCSI commands, allowing data to be transferred over long distances. Internet Small Computer System Interface (iSCSI) is an IP-based standard for connecting storage devices.
