Fig. 2 is a flowchart of a first specific implementation manner of step S102 in fig. 1 according to an embodiment of the present invention.
On the basis of the above-described embodiment, as shown in fig. 2, when the information of the Expander to be checked is the Zone configuration information, step S102: checking the information of the Expander according to a preset rule, and executing corresponding operation according to a checking result, wherein the method specifically comprises the following steps:
s201: judging whether an area Zone identifier (namely Zone ID) in the configuration information of the Expander is one of preset area Zone identifiers or not; if yes, go to step S202; if not, the process proceeds to step S204.
S202: judging whether the number of hosts actually supported by the Zone corresponding to the Zone identifier is consistent with the number of hosts preset and supported by the Zone; if so, the process proceeds to step S203.
S203: the Zone configuration information of the Expander passes the check.
S204: and sending an error signal (error) of the Zone configuration information.
The Zone function is to allow devices to communicate with each other by configuring a specific device to join a Zone, when a Zone is configured on a switch, devices in the same Zone can communicate with each other, and a device not joining any Zone cannot communicate with other devices.
When checking the Zone function, it should be checked whether the Zone in the configuration information of the Expander is one of the preset Zone zones, and whether the number of hosts supported by the Zone is consistent with the number of hosts supported by the preset Zone.
In general, the Expander of SAS (Serial Attached SCSI interface) supports 3 Zone zones, i.e., zone 1, zone 2, and Zone 3, which respectively correspond to different Zone IDs (e.g., 3, 1, and 4), and are normally in a "one-to-one", "one-to-two", and "two-to-eight" networking format.
Wherein, zone 1 supports 4 hosts +1JBOD,4 SAS interfaces are respectively set as ZID 9-12, and the Zone and ZID 1 can be accessed; all hard disks are set to be ZID 1, and can access the hard disks and ZID 9-12; the effect is achieved that 4 hosts cannot see each other, but can access each hard disk.
Zone 2 supports 1 host + multi-JBOD cascaded networking, 4 SAS interfaces are set to be ZID 1, and each SAS interface can access the ZID 1; all hard disks are set to be ZID 1, and the ZID 1 can be accessed; the effect that 1 host and more JBODs can see each other and can access each hard disk is achieved.
Zone 3 supports 2 hosts (x 8 bandwidth), 2 SAS interfaces are set to ZID 9,2 SAS interfaces are set to ZID 11, and the Zone can access the host and ZID 1 respectively; all hard disks are set to be ZID 1, and can access the ZID 9-12; the effect that 2 hosts can not see each other but can access each hard disk is achieved, and 2 SAS interfaces are connected to the same host, and the bandwidth can be integrated into x8.
It is checked whether the area Zone in the configuration information of the extender Expander is one of the preset area zones, i.e. whether the area Zone in the configuration information of the extender Expander is one of Zone 1, zone 2, zone 3 by means of the Zone ID. And checking whether the number of the hosts supported by the Zone is consistent with the preset number of the hosts supported by the Zone, and comparing the head configuration information with the preset Zone configuration condition after checking the head configuration information according to the Zone information. If the Zone in the configuration information of the Expander is Zone 1, it is checked whether the handpiece configuration information of the Zone information contains 4 host IDs.
Further, when the number of hosts actually supported in step S202 is not consistent with the preset number of hosts supported, the method for monitoring the Expander provided in the embodiment of the present invention may further include:
s205: judging whether the number of the hosts actually supported is larger than the number of the hosts preset to be supported; if yes, go to step S204; if not, the process proceeds to step S206.
S206: recording area Zone configuration information error information.
The situation that the number of hosts actually supported by the Zone is greater than the preset number of hosts is more serious than the situation that the number of hosts actually supported by the Zone is less than the preset number of hosts, when the number of hosts actually supported by the Zone is greater than the preset number of hosts, the Zone configuration information is reported to be wrong to prompt the staff to maintain in time, when the number of the hosts actually supported by the Zone is less than the preset number of the supported hosts, recording Zone configuration information error information so that a worker can conveniently check the information, or only carrying out error prompt without carrying out error warning.

S304: and sending a storage configuration information error reporting signal.
S305: checking whether the power-on states of all the hard disks are normal after power-on; if yes, go to step S303; if not, the process proceeds to step S304.
Cold storage generally refers to storage in which data is not accessed very much. Hot storage generally refers to storage where data is more active. In a specific implementation, the hot and cold storage setting may be found in the configuration information of the Expander, and specifically may be to look at the identifier at the corresponding byte, such as "0" for cold storage and "1" for hot storage.
And (3) aiming at the difference of the cold and hot storage settings of the Expander, executing different inspection methods, namely for the cold storage, checking whether the number of the powered-on hard disks of the cold storage is correct, and for the hot storage, checking whether the powered-on states of all the hard disks after being powered on are normal.
