HP StorageWorks 30 Modular Smart Array - Gathering Information to Troubleshoot EMS Events

Information

The customer received msamon EMS events reporting issues on an HP StorageWorks Modular Smart Array 30 (MSA30). The MSA30 was attached to an HP-UX host via an A6829A PCI Dual Channel Ultra 160 SCSI Host Bus Adapter.

ioscan –fn output:

NOTE: SCSI Target 15 is used by the SES chip/IO board and has the following device IDs:


MSA30-SB = COMPAQ PROLIANT 4L7E*SB
MSA30-DB = COMPAQ PROLIANT 4L7E*DB
MSA30-MI = COMPAQ PROLIANT 7L7E*DB

Online Diagnostics Support Tool Manager (STM) provides information for the drives but not for the enclosure.

Details

"The HP StorageWorks Modular SAN array 1000 / 30 Monitor (msamon) is designed to monitor the operation of storage devices on your system.

If msamon detects a problem with a disk array or Just A Bunch Of Disks (JBOD) (SCSI/SATA), it sends an event to the Event Monitoring Service (EMS). The EMS framework alerts you using one of the notification methods defined for the monitor. Events include a description of the problem, its causes, and the recommended solution.

The msamon monitor polls the device at regular intervals for the status of each disk array. Then, the monitor analyzes the data returned by the device to determine if a hardware problem has occurred. If an error that warrants notification has occurred, the monitor generates an event.

The monitor launches automatically along with the system. Therefore, it ensures that all supported disk arrays are protected from undetected hardware failure."

For this specific configuration, it is not possible to get more information by using STM other than the status of the drives.

The EMS event details provide the enclosure EMU firmware version:
