Watching for patches, service packs and revisions
Although keeping track of patches and revisions to operating systems and applications is usually seen as the province of system administrators or application administrators, it can be important to storage administrators as well.
According to Bill Peldzus, the storage consulting marketing manager for Imation's Storage Professional Services Group, one of the major causes of problems in installing storage systems is incompatibilities between the exact software and firmware configurations and the system. This is especially apparent in SANs, but it can be true in any storage system.
Part of the problem, Peldzus says, is that storage manufacturers are unable to check every possible combination and permutation of operating system and applications with their hardware, firmware or software. While something may generally work, there may be specific combinations that either aren't tested or simply don't work.
In tracking these down, it helps if the storage administrator has a complete list of all patches, service pack versions, and other revisions at his or her fingertips. Often the incompatibilities are known and trouble can be avoided or answers found more quickly with the information at hand.
