A pesquisa de localização padrão para a imagem de recuperação de BIOS está em uma unidade USB externa (se houver). Se uma unidade USB não estiver presente, a imagem de recuperação na unidade de disco rígido principal será usada.
A recuperação do BIOS 2 e 3 não é suportada de uma unidade de disco rígido criptografada ou se a senha da unidade de disco rígido estiver ativada no BIOS. A configuração da recuperação do BIOS tentará encontrar a imagem de recuperação na unidade de disco rígido, mas falhará.Se for possível entrar na configuração do BIOS, você pode tentar desabilitar a senha da unidade de disco rígido e tentar recuperar o BIOS.

The Exadata version installed on an Exadata storage server or an Exadata database server is determined with the imageinfo command. The image version of an Exadata release consists of three components. For example, if the command imageinfo -ver returns 12.1.2.1.1.150316.2, then:
Note that customizing the operating system by adding or updating packages may introduce problems when applying an Oracle Exadata System Software update because the non-Oracle software may add new dependencies which will not be provided by the Oracle Exadata System Software update. For this reason it is recommended to stay close to the Exadata Database Machine image and customize as little as possible.
A channel can be subscribed to by a local non-Exadata database server. Channel content is then downloaded to the local server and the repository is made available as a YUM repository which is used to update Exadata database servers. If no Internet connection is available from the data center or if ULN synchronization is not possible, then a ready-to-use YUM repository can be downloaded as an ISO image.
Do not use an Exadata database server as the local ULN mirror. Doing so may lead to dependency conflicts between the packages required by ULN to construct the repository, and the packages installed or updated on the Exadata database server by the Exadata software update. If no separate server is available, then use the ISO image method instead. See "Downloading the ISO Image as a YUM Repository from My Oracle Support and Passing the Location of the Compressed Image to the Update Utility".
You can download, uncompress, and place the ISO image channel holding the Oracle Exadata software update on a web server that has HTTP connectivity to every Oracle Exadata database server. This method is recommended for the following conditions:
With exadata-sun-computenode-exact rpm, the system appears as if it were freshly imaged to the newer release because all the Oracle Exadata packages are exactly the same as on a vanilla installation. The exadata-sun-computenode-minimum rpm, however, sets the minimum dependencies, and enforces that all packages are installed, but it also allows packages to be at a later version. A vanilla installation always starts with both RPMs. To allow customization or updates, you need to remove exadata-sun-computenode-exact.
For regular and virtualized Exadata database servers (domU), when the active system image is running from a file system on /dev/mapper/VGExaDb-LVDbSys1, the backup is made onto /dev/mapper/VGExaDb-LVDbSys2 (and vice versa). For Exadata database servers running dom0 with /dev/mapper/VGExaDb-LVDbSys2 as the active image, the backup goes to /dev/mapper/VGExaDb-LVDbSys3 (and vice versa).
This means that upon rollback of an update the active system image for regular database servers and domU will become /dev/mapper/VGExaDb-LVDbSys2, and for dom0 will become /dev/mapper/VGExaDb-LVDbSys3.
Firmware updates are not rolled back when rolling back to a previous image. The Oracle Exadata System Software releases support later firmware releases. After rolling back, run the following commands to apply older firmware versions when needed:
You can roll back updated Exadata storage servers only when they are updated successfully. This means the imageinfo command must return success for active image status. Storage servers with incomplete or failed updates cannot be rolled back. Rollbacks can be done in a rolling or non-rolling fashion.
Following any upgrades to the server image (using dbnodeupdate or patchmgr), check the JDK version. If the JDK package is reverted to an older version during the upgrade, then use the procedures here to update the JDK package to the latest version.
Following any upgrades to the server image (using dbnodeupdate or patchmgr),check the JDK version. If the JDK package is reverted to an older version during the upgrade, then use the procedures here to update the JDK package to the latest version.
Check image status and history using the imageinfo and imagehistory commands on each cell. A successful update to a system with high capacity or high performance drives shows output similar to the following.
OverviewOriginally the IBM POWER HMC was sold only as an integrated appliance that included the underlying hardware as well as the HMC firmware. IBM extended the POWER HMC offering to allow the purchase of the traditional hardware appliance (for example, model 7042/7063) or a firmware only virtual HMC machine image. The virtual HMC (vHMC) offering allows clients to use their own hardware and server virtualization to host the IBM supplied HMC virtual appliance.Product identification number

Note that service pack/iFix binaries are identical for a given platform (x86 or POWER). The PTFs for vHMC on x86 and PTFs for 7310/7042 machine types are the same and can be used interchangeably. Likewise, PTFs for vHMC on POWER and the PTFs for 7063 machine type are the same. PTFs for vHMC on x86/7042 machine type cannot be used with vHMC on POWER/7063 and vice versa. The four fix central categories are provided due to differences in install media/images.Upgrading HMCvHMC can be upgraded by using the same network upgrade process as the hardware appliance. Instructions and images for upgrading via a remote network install can be found here:HMC V8 network installation images and installation instructionsSupport for vHMCSince the hardware and server virtualization is supplied by the client to run the HMC virtual appliance, this infrastructure that actually hosts the HMC virtual appliance is not monitored by IBM. Serviceable events related to the vHMC firmware are monitored however "call-home" for these events is disabled. For further information see document Callhome on HMC Serviceable Events is Disabled on vHMC at -01.ibm.com/support/docview.wss?uid=nas8N1020960The HMC virtual appliance continues to monitor the managed Power Systems hardware just like the HMC hardware appliance. Both HMC form factors provide remote notification and automatic call-home of serviceable events for the managed Power Systems servers.Support for vHMC firmware, including how-to and usage, is handled by IBM software support similar to the hardware appliance. When contacting IBM support for vHMC issues specify "software support" (not hardware) and reference the vHMC product identification number (PID: 5765-HMV).How-to, install, and configuration support for the underlying virtualization manager is not included in this offering. IBM has separate support offerings for most common hypervisors which can be purchased if wanted.Q&AQ: How can I tell if it is a vHMC?A: To determine if the HMC is a virtual machine image or hardware appliance, view the HMC model and type. If the machine type and model is in the format of "Vxxx-mmm" then it is a virtual HMC.From command-line (CLI) use the lshmc -v command and check the *TM field for a model starting with "V" and/or the presence of the *UVMID fields:*TM V8d7-f9d*SE fa6e3fc*MN IBM*PN N/A*SZ 8390283264*OS Embedded Operating Systems*NA 9.5.66.40*FC ????????*DS Platform Firmware*RM V8R8.4.0.0*UVMID 8d7f:9dfa:6aa6:e3fcIn the legacy GUI: From Welcome panel hover the mouse over "HMC Version" link; or from the Updates panel under the HMC Code Level section.In the enhanced GUI, click Help (the "circle ?" in the upper right) > AboutQ: Are existing HMC customers entitled to vHMC?A: No. vHMC is a separate offering and must be purchased separately. There is no conversion and no upgrade offering.Q: Can x86 based vHMC licenses (5765-HMV) be converted to POWER vHMC (5765-HMA)?A: No. They are two different offerings.Q: Are there any restrictions related to onsite warranty support for managed servers?A: Restrictions are similar to the hardware appliance- You must supply a workstation or virtual console session located within 8 meters (25 feet) of the managed system. The workstation must have browser and command-line access to the HMC. This setup allows service personnel access to the HMC.- You should supply a method to transfer service-related files (dumps, firmware, logs, etc) to and from the HMC and IBM service. If removable media is needed to perform a service action, you must configure the virtual media assignment through the virtualization manager or provide the media access and file transfer from another host that has network access to HMC.- Power vHMC cannot manage (nor service) the server it is hosted on.Q: Can the vHMC be hosted on IBM POWER servers?A: Yes, the 5765-HMA product allows vHMC to run on POWER8 servers with firmware 830 or later and POWER9 and later.Q: What restrictions are unique to vHMC on POWER?A:- POWER vHMC cannot manage the server it is hosted on.This implies the hosting POWER server must be managed by Novalink or another HMC instance. IVM-managed servers are not supported.- The HMC Virtual Appliance for PowerVM does not provide graphics adapter support for adapters assigned to the partition. "Local console" access is limited to command-line only. 2ff7e9595c
