General troubleshooting

If you have a problem with the CCI software, first make sure that the

problem is not being caused by the UNIX/PC server hardware or software,

and try restarting the server.

Problem

Recommended action

Deprecated

SCSI ioctl

The following

message is

output to syslog

file(/var/log/

messages) with

every ioctl():

program 

horcmgr is 

using a 

deprecated 

SCSI ioctl, 

please convert 

it to SG_IO

CCI currently uses the ioctl(SCSI_IOCTL_SEND_COMMAND) for

sending the control command to the command device. However, in

RHEL 4.0 using kernel 2.6.9.

xx

, the following message is output to

syslog file(/var/log/messages) with every ioctl():

program horcmgr is using a deprecated SCSI ioctl, please 

convert it to SG_IO

This can originate from the following kernel code in drivers/scsi/

scsi_ioctl.c as way of warning that ioctl(SCSI_IOCTL_…) of kernel

2.6.9.

xx

 does not properly handle an error of the HBA driver.

--------------------------------------------------------------

--------
/* Check for deprecated ioctls ... all the ioctls that do not 

follow

the new unique numbering scheme are deprecated */
        switch (cmd) {
        case SCSI_IOCTL_SEND_COMMAND:
        case SCSI_IOCTL_TEST_UNIT_READY:
        case SCSI_IOCTL_BENCHMARK_COMMAND:
        case SCSI_IOCTL_SYNC:
        case SCSI_IOCTL_START_UNIT:
        case SCSI_IOCTL_STOP_UNIT:
           printk(KERN_WARNING "program %s is using a 

deprecated SCSI "
                 "ioctl, please convert it to SG_IO\n", 

current->comm);
--------------------------------------------------------------

-------

Thus, CCI supports a way to change to the ioctl(SG_IO)

automatically, if Linux kernel supports the ioctl(SG_IO) for horcmgr

and 

inqraid

 command. However, CCI might encounter Linux kernel

that does not support the ioctl(SG_IO) fully, so CCI also supports by

defining either following environment variable or "/HORCM/etc/

USE_OLD_IOCTL" file(size=0) that uses the

ioctl(SCSI_IOCTL_SEND_COMMAND) forcibly. For example:

export USE_OLD_IOCTL=1
horcmstart.sh 10

HORCM/etc:
-rw-r--r--  1 root root      0 Nov 11 11:12 USE_OLD_IOCTL
-r--r--r--  1 root sys   32651 Nov 10 20:02 horcm.conf
-r-xr--r--  1 root sys  282713 Nov 10 20:02 horcmgr

CCI cannot be

started because

horcmstart

command fails

If you have changed the configuration definition file settings: make

sure that the configuration definition file you changed is correct.
If you have changed the settings of the storage system: make sure

that the settings you changed are correct, and if necessary, change

the configuration definition file settings.
Even if there are no problems in these files and settings, but if you

cannot run CCI, get all log files under the specified directory by

9-2
