2 SANtools® S.M.A.R.T. Disk Monitor (SMARTMon-UX) 1 Using S.M.A.R.T. Disk Monitor 1.1 General Overview S.M.A.R.T. Disk Monitor [Currently at release 1.43] (also referred to as SMARTMon-UX for UNIX, and SMARTMon for Windows in this document) is part of the SANTOOLS family of utility programs that monitors your disk hardware with the goal of identifying disks that have a strong possibility of crashing.

Using S.M.A.R.T. Disk Monitor 3 SMARTMon-UX for SPARC Solaris supports Solaris versions 2.7 and above. (Version 2.6 may still work, but we no longer test on that platform) SMARTMon-UX for HP's Tru64 requires version 5.1 (but may run on previous versions depending on your hardware). SMARTMon-UX for i86 Solaris (for Intel and compatible processors) supports Solaris versions 2.7 and above. SMARTMon-UX for IRIX supports IRIX versions 6.5 and above.

4 SANtools® S.M.A.R.T. Disk Monitor (SMARTMon-UX) the operator supplies the program with a list of devices to run against, the program builds that list and issues the commands to verify that the devices exist and are not offline. If no list of devices is supplied, the software will initiate a device discovery. This discovery can take several seconds up to over a minute if you have a large UNIX configuration.

Using S.M.A.R.T. Disk Monitor · · · · · · · 5 Not all disk drives support the performance bit (also known as PERF bit). SMARTMon will let the user know if there is a problem setting this value. The S.M.A.R.T. polling interval is the internal interval programmed into the disk drive. This is set to 10 minutes, unless changed via the command line option -F 18 . The disk is checked to see if it supports optional SMART and temperature reporting log pages. If so, they are read to establish a baseline.

Device Polling: After all devices have been discovered, they will be polled at a configurable interval.

If the value read is greater than or equal to the threshold, the appropriate action (email, event log, and/or user-defined script) is taken. The process continues until all thresholds have been examined. The program sleeps until the next polling period. Windows Service Program Startup As of release 1.

Using S.M.A.R.T. Disk Monitor 11 Generally this is the case. Unless you use this function to select and modify email servers and accounts, the email server may reject the message. 4. What happens if there are more than one email accounts set up for a particular SMTP server? The software will use the first entry (lowest number) it finds that matches the SMTP server which was supplied via the command-line when the program was launched. 5.

Unlike SES enclosures, SAF-TE enclosures have a unique SCSI ID and LUN associated with them. The internal mechanism and commands that SMARTMon has to use to determine the health of a SAF-TE enclosure are different from those commands used to communicate with a SES enclosure.

SMARTMon-UX does not care what disk you flash, other than checking to see if it is supported. If you want to flash your boot disk, and have it spin down for a few minutes and not service I/O commands, the software will not stand in your way.

No. We have no idea what firmware image you need. If you have to ask this question, we feel that you should not be changing firmware in the first place.

Using S.M.A.R.T. Disk Monitor 105 When to Reassign Blocks (SCSI family disks only) SMARTMon-UX makes it easy for you to know when you have blocks that must be forcibly reassigned. Just run either the self-test (-steb 108 , or -scrub 118 family) commands, and they will report if any blocks have unrecovered errors that should be reassigned. The advantage of using the -steb 108 test is that this is a built-in test and does not consume any host bandwidth.

The data integrity tests are most useful for storage professionals who want to qualify hardware, test RAID controllers, and insure data is in tact after stressing the storage, such as after a controller or HBA fail over test. System administrators should consider running this test in qualifying hardware. You would not ordinarily run this as part of any scheduled maintenance.

If you want every block of the disk to be zeroed, set hexbyte to 00.

142 SANtools® S.M.A.R.T. Disk Monitor (SMARTMon-UX) · We have sometimes seen that the HBA never responds, or that the program will lock up (but not your computer) when using the -fc 128 or -fcping 140 commands. This is due to bugs in the API, or not having the latest firmware and/or drivers for your HBA loaded. Please report this information both to us, and to your HBA supplier to get them resolved. Often, if you just upgrade to the most current HBA drivers then the problems and lockups go away. 1.

Developed through the Storage Networking Industry Association (SNIA), the HBA API has been overwhelmingly adopted by Storage Area Network vendors to help manage, monitor, and deploy storage area networks in an interoperable way. The HBA API is implemented as a set of 'C' level API's which allow access to low level, Fibre Channel HBA information in a platform- and vendor- independent way.

If you use the /dev/sd class driver, you are limited to the first 510 defects, which is rarely enough for large disks. The software now reports a disk is dead if it responds with ASC=40 or 44 on SMART queries. This would generally happen some time after a predictive S.M.A.R.T. error was reported, and the drive has failed to the extent that it cannot run predictive tests.
