-d Specifies a device-T Specifies the certify taskv Certify Hard file Attached to a Non-RAID and PCI-X RAID SCSI AdapterFor pdisks and hdisks, this selection reads all of the ID and data fields on the hard file. If bad-dataerrors are encountered, the certify operation counts the errors.If there are non-recovered data errors that do not exceed the threshold value, do one of the following:For hdisk hard files, the hard file must be formatted and then certified again.For pdisk hard files, diagnostics should be run on the parent adapter.If the non-recovered data errors, recovered data errors, recovered and non-recovered equipment errorsexceed the threshold values, the hard file must be replaced.After the read certify of the disk surface completes for hdisk hard files, the certify operation performs2000 random-seek operations. Errors are also counted during the random-seek operations. If a disktimeout occurs before the random seeks are finished, the disk needs to be replaced.The Certify service aid displays the following information:– For hdisks:- Drive capacity in megabytes.- Number of data errors recovered.- Number of data errors not recovered.- Number of equipment checks recovered.- Number of equipment checks not recovered.– For pdisks:- Drive capacity in megabytes.- Number of data errors not recovered.- Number of LBA reassignments- Number of equipment checks not recovered.This task can be run directly from the AIX command line. The command line syntax is: diag -c -ddeviceName -T "certify"FlagDescription-c No console mode-d Specifies a device-T Specifies the certify taskv Certify Hard File Attached to a PCI SCSI RAID AdapterThis selection is used to certify physical disks attached to a PCI SCSI RAID adapter. Certify reads theentire disk and checks for recovered errors, unrecovered errors, and reassigned errors. If these errorsexceed the threshold values, the user is prompted to replace the physical disk.This task can be run directly from the AIX command line. The command line syntax is: diag -c -dRAIDadapterName -T "certify {-l chID | -A}"FlagDescription-c No console mode-d Specifies the RAID adapter to which the disk is attached-T Specifies the certify task and its parameters-I Specifies physical disk channel/ID (for example: -l 27)-A All disksChapter 2.
