Engineers in strict accordance with the Oceanstor 9000 software installation and operation guide are to complete the pre-inspection and configuration, the software deployment process displayed ome exceptions, the following treatment is appropriate (multiple choice)
- For the “configuration operating system failed” error, check the node / var / log partition and clean up the partition, initialize the system, and then re-run the software deploy
- If it is not a failure, restart the deployment after reinstalling the deploy deployment package
- After the deployment fails, run the sh /opt/huawei/deploy/script/clean.sh command on each node to initialize the system and restart the software department
- After deployment abnormalities, reboot all nodes, reinstall oceanstor tookit, and start the software deployment

An MSCS Two-Node Cluster Interconnects with Disk Arrays via the iSCSI Protocol in a Multipathing Environment and Multipathing Software installed on Each Node. You build the cluster configuration using the wizard and part of the description shows that the quorum disk and resource disk can not be online. The following statement is correct regarding this scenario:
- The shared disk file system uses the GPT format that caused the quorum disk to fail Online
- The quorum disk can not be online due to the cluster feature that does not enable multipathing software
- The MSCS Cluster service does not bring the volume resource online. The resource disk can not be online
- Heartbeat network timeout causes arbitration disk and resource disk probability online
-
Which of the following is correct regarding the Oracle RAC deployment installed Grid package? (multiple choice)
- To check the cluster node use the command:
olsnodes -n - To check the cluster status use the command:
crsctl check cluster -all
crsctl check crs - To check cluterware resource status use the command:
crsctl stat ser -t - To check oracle ASM operating status use the command:
ocrcheck
- To check the cluster node use the command:
-
Using Simpana to achieve a complete Exchange backup requires at least which of the following components? (Multiple choice)
