Continue to write new data to the file system after the file system is damaged

The hard disk is divided into chunks.

Lun consists of extend or grain

A CKG chunk may come from the same hard disk.

Chunk in a CKG may come from a different storage pool.

After a snapshot of the LUN of the redundancy site is created, the snapshot is not activated at the same time.

Disaster recovery storage side of thedatabase resides in the cache has not been written to the hard disk.

When creating a snapshot on the disaster recovery end LUN, the production end is copying data to the disaster recovery end.

The production end and disaster recovery end adopt the disaster recovery solution of incremental LUN copy. The incremental data is abnormally interrupted during the synchronization process and has not been repaired.

Rsize / wsize, read and write the maximum size of each block, it is recommended to adjust to the maximum. General Linux operating system environment, the maximum value of 1M.

Async, allowing asynchronous data write, synchronous write requirements. NFS server must brusheach data into the hard disk before it can return success delay higher.

Noatime, if you do not need to record the file access time, you can increase this parameter to avoid frequent access, modify the access time to open pin.

Nolock, if there is a shared file between NFS clients, you can use this parameter. Reduce service-side file lock overhead.

The automatically created Asynchronous Remote Copy snapshot can either be a private quick pick or a public one.

In a DR scenario, it is recommended to create a virtual snapshot of the secondary LUN and map it to the host for access.

In remote replication link networking, parallel networking is better than crossover networking.

The number of LUNs in the consistency group should be as small as possible, and only the LUNs that have write dependencies on the same application are placed in a consistency group.

The backup server and the media server can not communicate properly.

The link between the backup media and the media server is down.

Backup server SQL database failure.

DDB is abnormal.

Manually clear the NMS alarm and turn off the alarm light.

Observe thesymptom and collect the fault information.

Troubleshoot according to the "Event Reference" or "Troubleshooting" manual.

Maintain the faulty environment and contact technical engineer for support.

Stop the current production business, delete the host mapping.

Adding the remote device to the original production side array.

With the disaster recovery array as themaster LUN and the original production array as the slave LUN, create the remote replication relationship between the DR and the production end and wait for the initial synchronization to be completed.

Make an incremental synchronization.

Delete theoriginal production array consistency group.

VxFS is a non-log file system that can support more than2T files.

File system snapshot using copy-on-write (copy-on-write technology) and other files together, share partition or volume storage space.

Provide file system-level snapshots, copy.

File System Snapshots, Scenarios, Replication, etc. Features are based on Storage Checkpoint.

It is an object-based approach to data replication

ROW snapshots are based on the cyclical manner ofdata replication

It can be manually set off by the user or system timing synchronization starting

It supports the Quota quota information of the main file system to the slave, no need to configure the quota.

When using the InfoEqualizer function, you need to configure DNS. If you use an external DNS server, when configuring the DNS server, there is a setting of "reverse lookup zone name", network ID setting in this tab, you need to input network ID in reverseorder.

When there is a DNS server in the user network, the DNS server in the user network does not need to configure the forwarding record. When the user network without DNS service server, configure the InfoEqualizer DNS IP address as the DNS server'saddress on the client.

The root domain name is the domain name InfoEqualizer configured for the cluster. This domain name must be configured as the fully qualified domain name, that is, the domain name that includes the root node.

The domain name ofthe partition is configured as the relative domain name, and the root domain name of the InfoEqualizer is automatically taken as the suffix of the domain name, and the full name of the domain name is formed with maximum support of 32 partitions.

The server initiates the establishment of a data connection request

The FTP client uses the pasv command to tell the FTP server its own IP and port number

FTP server uses the pasv command to tell the FTP client's own IP and port number

The target port number that initiated thedata connection request may be 29999

One Ethernet port can create multiple logical ports

If Ethernet ports A and B are added to VLAN 2, by default the ports A and B data are in the same drift group

If binding port A and physical port B join a unified VLAN, as long as there is a physical port in bonded port A, the service will switch to Physical Port B

When the IP drift mode is set to "Manual", when the port is restored, and the active port link is in a normal state for more than one minute, the system can cut back the service to the main port.

Host to the optical switch connection is abnormal.

When configuring the zone on the switch, configure the FC port and the host port that works in the working mode of the VIS6600T as a target in one zone.

The working mode of the VIS6600T is abnormal because the initiator's FC port is connected to the optical switch.

In the working mode of VIS 6600T, the connection between the FC port of the target device and the optical switch is abnormal.

Dynamic domain name, which returns the dynamic IP address of the node for the client, supports the failover function and is recommended for CIFS protocol sharing

Static domain name, which returns the domain name of the node's static external IP address to clients, is recommended for NFS protocol sharing

dynamic external IP address, node failure, the dynamic IP address can be automatically assigned to other working nodes, the client can passagainThis IP address is connected to the OceanStor 9000

static external IP address, the node fails, the client can not access the oceanstor 9000 through the IP address

UniformView softwareinstalled by the user can specify a directory, create a UniformView directory in this directory as a mounted root table of Contents

The administrator performs a mount command on the UniformView client to mount a different storage domain with the clusterID and the static IP address

UniformView Resolve mount command, in the mount root directory, followed by the creation of a cluster ID name of the directory

Using the NFS protocol, mount the specified shared directory to the cluster ID directory read-only using the management IP address

To improve the reliability of the video data storage device, the user turns on the securevideo feature of the data disk using a 4 + 1 protection level

The user turns on the securevideo feature, with two data corruptions if the data disk uses a 4 + 1 protection level and only 3 for a write operation

Users open the securevideo feature data consistency scanning, the system does not complete the data files, will be cleaned up

After the user turns on the securevideo feature, the file corruption event has been reported while reading and writing files, and the data recovery failure alarm is no longer reported

Recovery of the RAID group can be done by recovering the first failed hard disk

Recoveryof the RAID group can not be done by recovering the first failed hard disk

Use3-tier Tier, 1TB high performance layer, 4TB performance layer, 10TB capacity layer, and configure LUN1 to allocate high-performance layer capacity first, LUN2 preferentially allocates performance layer capacity and LUN3 preferentially allocates capacitylayer capacity

Use 3-tier Tier, 1TB high-performance layer, 4TB performance layer, 10TB capacity layer, configure LUN1 and LUN2 to migrate automatically, and LUN3 priority allocation of low-performance layer capacity

The use of 3-tier Tier, high-performance layer 1TB, performance layer is 4TB, capacity layer is 10TB, while configuring LUN1, LUN2, LUN automatic relocation. The LUN3 is migrated preferentially to the low-performance layer

Set the monitoring period of the Smart tier to 8:00 to 18:00 every day from Monday to Friday. The migration period is not overlapped with the monitoring period

Before plugging and unplugging the controller, make sure that the service is stopped or has switched to the peer controller
