El conocimiento al alcance de todos.

 Thank to: https://community.hpe.com/ One of our very Linux-savy SE's put together a collection of install guides for various version of Linux. Below are the content for CentOS / RHEL 6. I used these steps during my last Linux installation and they worked nicely. 1) Configure Ethernet Interfaces to be used for iSCSI data      Set MTU to 9000 if jumbo desired           edit /etc/sysconfig/network-scripts/ifcfg-ethX (X is interface number)           DEVICE=eth1           BOOTPROTO=static           BROADCAST=10.10.50.255           IPADDR=10.10.50.101           NETMASK=255.255.255.0           NETWORK=10.10.50.0       ...

Thinly Provisioned y Thickly Provisioned son dos términos utilizados en el ámbito del almacenamiento de datos para describir diferentes métodos de asignación de espacio en disco. Aquí están las diferencias detalladas entre ambos: Thinly Provisioned (Asignación Delgada) : Definición : En un entorno de almacenamiento thinly provisioned, el espacio en disco se asigna dinámicamente a medida que se necesite. Es decir, los recursos de almacenamiento se asignan solo cuando los datos son escritos en el disco. Ejemplo : Supongamos que se crea un volumen de almacenamiento de 1 TB. Inicialmente, este volumen podría tener solo unos pocos gigabytes de datos escritos en él. En un entorno thinly provisioned, solo se asignaría espacio para esos pocos gigabytes de datos escritos, en lugar de asignar todo el 1 TB de espacio desde el principio. Ventajas : Permite un uso más eficiente del espacio en disco, ya que no se desperdicia espacio no utilizado. Además, proporciona una mayor flexibilidad al permiti...

Thanks to: https://winteladmin.com/ error: Port enc0:iobay1:d3 pause-flood detected and automatically disabled Host was not reachable on network. When checked on ILO server is up and running. When I try to ping the server its unresponsive.Host is a blade server, hence suspected an issue with the network module. Therefore, connected virtual connect. Found one of the virtual connect module was degraded. When analysed the HP Virtual connect found an error message stating “Port was disabled because a pause flood was detected” Further to this when validated the server port assigned to the bay1/bay2 found the status “Not Linked/Pause Flood Detected”. It confirms the issue was caused by pause Flood. In some cases, a flex-10 port can enter into disabled state due to the triggering of “pause-flood”, or network-loop. You can confirm the same port status using Virtual Connect Manager CLI. Connect to Virtual connect using SSH and Execute the below command: Show port-protect This woul...

Thanks to: https://community.hpe.com/ It depends on how large the virtual volumes were. Each CPG has a growth size. This lets the CPG keep some chunklets pre-reserved. Also, when volumes are deleted, it will retain some space in the CPG assuming the space will be reused. Try compacting your CPGs: compactcpg -f -pat * The following command will set up a job to run weekly (Sundays, 0000 hours): createsched -no_alert "compactcpg -f -pat *" @weekly Compact_All_CPGs
