Here are the available SCSI exerciser functions:
Table 5·6. SCSI Exerciser Functions
Key Exerciser Description
@)
Device selection; Allows a new device to be selected.
®
Read check entire disk. Each pass can take a half hour or more, depending
on the capacity and speed of the disk. The number of passes are determined
by the 'N' command. This command reads 64K bytes in each read operation.
A butterfly pattern is used, with successive read operations alternating from
the next lowest unread address to the next highest unread address until the
entire disk has been read tested. If an error occurs, the logical blocks within
the 64K block are read successively. For each logical block that can not be
read, an error is reported, and if autosparing has been selected, the block is
spared.
®
Block read. Display the contents of the disk block in hex.
®
Select the number of passes that the read or Write function are to make.
CD Display the inquiry data and the capacity of the disk.
CD
Display the drive's log information. This function is only available on HP
fixed drives. It uses the Access Log HP specific SCSI command to report the
data logged by the disk drive itself.
®
Run Self-test. This can take up to a minute on some drives. Note that if it is
run on the root disk, the controller will effectively lock up until the test
completes. The operations performed by this self-test vary from drive to
drive, but it is not destructive.
©
Enter CE mode. The user is prompted for a password, which is the same as
the password used to enter CE mode in the CSSO exerciser. This mode
allows the user to perform tasks which can erase data on the disks.
@)
Exit the program.
