unblock Use the unblock function to gain access to a blocked logical drive. RAID level-0 logical drives become blocked if they are in an array that contains RAID level-1 or level-5 logical drives and the array is being rebuilt. Because the RAID level-0 logical drives cannot be rebuilt, the data stored on the RAID level-0 logical drives is damaged and should not be accessed. After you issue the unblock function, you must re-create or restore the data previously stored on the RAID level-0 logical drives. Supported operating systems: Windows NT, Windows 2000, OS/2, NetWare, Linux, OpenServer, UnixWare, and DOS Command: ipssend unblock controller drivenum where: • controller is the ServeRAID controller number (1-12) • drivenum is the logical drive number (1-8) Problem-isolation and debug functions The IPSSEND problem-isolation and debug functions include the following: certify Use the certify function to verify the media of a physical drive.

unblock

Use the

unblock

function to gain access to a blocked logical drive. RAID

level-0 logical drives become blocked if they are in an array that contains

RAID level-1 or level-5 logical drives and the array is being rebuilt. Because

the RAID level-0 logical drives cannot be rebuilt, the data stored on the RAID

level-0 logical drives is damaged and should not be accessed. After you issue

the

unblock

function, you must re-create or restore the data previously stored

on the RAID level-0 logical drives.

Supported operating systems: Windows NT, Windows 2000, OS/2, NetWare,

Linux, OpenServer, UnixWare, and DOS

Command:

ipssend unblock

controller drivenum

where:

•

controller

is the ServeRAID controller number (1

–

12)

•

drivenum

is the logical drive number (1

–

Problem-isolation and debug functions

The IPSSEND problem-isolation and debug functions include the following:

certify

Use the

certify

function to verify the media of a physical drive. When

the program finds a media error, it reassigns the sectors. A summary

of reassignments and PFA errors appears upon completion of the

verification.

Supported operating system: DOS

Command:

ipssend certify

controller channel sid

where:

•

controller

is the ServeRAID controller number (1

–

12)

•

channel

is the channel number for the device (1, 2, 3, or 4)

•

sid

is the SCSI ID for the device (0

–

15)

eraseevent

Use the

eraseevent

function to clear all logged entries in the

designated event log. See

getevent

help for information about the

contents of the device event log and the controller soft and hard event

logs.

Supported operating systems: Windows NT, Windows 2000, OS/2,

NetWare, Linux, OpenServer, UnixWare, and DOS

Command:

ipssend eraseevent

controller options

where:

•

controller

is the ServeRAID controller number (1

–

12)

•

options

is the designated event log:

—

DEVICE for the device event log

—

SOFT for the ServeRAID controller soft event log

—

HARD for the ServeRAID controller hard event log

getbst

Use the

getbst

function to display the number of bad stripes in the

bad stripe table for each logical drive.

Supported operating systems: Windows NT, Windows 2000, OS/2,

NetWare, Linux, OpenServer, Unixware, and DOS

Command:

ipssend getbst

controller

where:

controller

is the ServeRAID controller number (1

–

12)

format

Use the

format

function to perform a low-level format of a physical

drive.
