show disks
SMART support is vendor and drive technology (IDE, SCSI, and Serial Advanced Technology
Attachment [SATA] disk drive) dependent. Each disk vendor has a different set of supported SMART
attributes.
Even though SMART attributes are vendor dependent there is a common way of interpreting most
SMART attributes. Each SMART attribute has a normalized current value and a threshold value. When
the current value exceeds the threshold value, the disk is considered to have “failed.” The WAAS
software monitors the SMART attributes and reports any impending failure through syslog messages,
SNMP traps, and alarms.
To display SMART information, use the show disks tech-support EXEC command. To display more
detailed SMART information, enter the show disks tech-support details EXEC command. The output
from the show tech-support EXEC command also includes SMART information.
Examples The following is sample output from the show disks failed-sectors command. It displays a list of failed
sectors on all disk drives.
WAE# show disks failed-sectors
disk00
