How effectively it’s required to use the Health Check Commands on storage array tools?
Large service delivery accounts also find it difficult to conduct health checks and track power on hundreds of arrays and switches scattered across the globe, in various places, in different environments. Which may be cloud distribution accounts that help multiple SAN environments, either customer-dedicated or shared by multiple customers; or multiple SAN environments that result from a merger or acquisition. A health check report is prepared several times a day to guarantee the Service Level Agreement (SLAs) so that the arrays can be closely monitored and to ensure that all faults are treated properly. This is a repetitive and time-consuming job that involves the efforts of several engineers dedicated to this mission. The difficulty is increasing as the fabrics can be spread through environments and locations. Moreover, due to the complexity of the arrays and switches, the purpose of monitoring the entire environment that not be one single device.
The basic health check commands for various arrays are discussed in this section.
