摘要： A method is used in managing drive problems in data storage systems. It is determined, by a physical drive object, whether an I/O with a drive is able to be retried by another object. An overall retry time for the I/O is tracked. If the overall retry time is excessive, the drive is taken offline.

摘要： Described are techniques for performing a firmware update. A drive management object determines one or more physical drives matching criteria of a first received request. The drive management object sends to provision drive objects a second request to update firmware on physical drives. Firmware update processing is performed independently for each physical drive. Each provision drive object is associated with one of the physical drives. Firmware update processing for said one physical drive includes determining whether to perform the firmware update at a current point in time; in response to determining to perform the firmware update at the current point in time, performing preparation processing; notifying, upon completion of said preparation processing, a physical drive object associated with said one physical drive to download the firmware update to the one physical drive; and resuming I/O operations to the one physical drive upon successfully completing the firmware update.

摘要： A method is used in analyzing drive errors in data storage systems. An error tag and total good I/O count are maintained for a drive. For each failed I/O, the following is performed. An error weight per error is retrieved. A new error tag is calculated from the error weight, a previous error tag, and the total good I/O count. An error ratio is calculated from the new error tag and a total I/O count. The error ratio is compared with thresholds. If one or more of the thresholds has been crossed, action is taken on the drive. The error tag is reduced as good I/O is produced.
