Monitoring raid status using sas3ircu IR Volume State values are as follows*: - Okay (OKY) – The volume is active and drives are functioning properly. User data is protected if the current RAID level provides data protection. - Degraded (DGD) – The volume is active. User data is not fully protected because the configuration has changed or a drive has failed. - Failed (FLD) – The volume has failed. - Missing (MIS) – The volume is missing. - Initializing (INIT) – The volume is initializing. - Online (ONL) – The volume is online. Physical device State values are as follows: - Online (ONL) – The drive is operational and is part of a volume. - Hot Spare (HSP) – The drive is a hot spare that is available to replace a failed drive in a volume. - Ready (RDY) – The drive is ready for use as a normal disk drive, or it is ready to be assigned to a volume or a hot spare pool. - Available (AVL) – The drive might not be ready, and it is not suitable for use in a volume or a hot spare pool. - Failed (FLD) – The drive failed and is now offline. - Missing (MIS) – The drive has been removed or is not responding. - Standby (SBY) – The device is not a hard-disk device. - Out of Sync (OSY) – The drive, which is part of an IR volume, is not in sync with other drives that are part of the volume. - Degraded (DGD) – The drive is part of a volume and is in degraded state. - Rebuilding (RBLD) – The drive is part of a volume and is currently rebuilding. - Optimal (OPT) – The drive is optimal and is part of a volume. Physical device Drive Type values are as follows: - SAS_HDD – The drive is a SAS HDD. - SATA_HDD – The drive is a SATA HDD. - SAS_SSD – The drive is a SAS SSD. - SATA_SSD – The drive is a SATA SSD. Physical device Protocol values are as follows: - SAS – The drive supports SAS protocol. - SATA – The drive supports SATA protocol. *Sourse info: https://docs.broadcom.com/doc/12353382
