Change IP of iDRAC from linux


If you install OpenManage onto the host, you can apply an IP address to the iDRAC that way. OpenManage would provide a graphical tool, but if this is a headless install, it would also provide the racadm command set. 

racadm setniccfg -s <IPv4 address> <Subnet> <IPv4 Gateway>

Fixing Postfix permission issues on Linux

If you are receiving a message similar to…

Jan 15 22:12:36 ip-10-0-0-133 postfix/postdrop[8301]:warning: mail_queue_enter: create file maildrop/939392.8301: Permission denied

Jan 15 22:12:37 ip-10-0-0-133 postfix/postdrop[8302]:warning: mail_queue_enter: create file maildrop/8821.8302: Permission denied

Jan 15 22:12:37 ip-10-0-0-133 postfix/postdrop[8303]:warning: mail_queue_enter: create file maildrop/14290.8303: Permission denied

You probably have a permission issue with your Postfix installation.  This is usually caused by a bad upgrade or maybe user error when moving or recovering mail folders.
This can easily be solved by running the following commands below as root.

/etc/init.d/postfix stop

killall -9 postdrop

chgrp -R postdrop /var/spool/postfix/public

chgrp -R postdrop /var/spool/postfix/maildrop

/usr/sbin/postfix set-permissions

postfix check

/etc/init.d/postfix start

This should work on just about any Linux distro.

scsi disk 삭제 방법

rhel 기준이며 잘안될때는 재기동이 짱입니다 ㅠㅠ

Procedure 1. Ensuring a Clean Device Removal

Close all users of the device and backup device data as needed.

Use umount to unmount any file systems that mounted the device.

Remove the device from any md and LVM volume using it. If the device is a member of an LVM Volume group, then it may be necessary to move data off the device using the pvmove command, then use the vgreducecommand to remove the physical volume, and (optionally) pvremove to remove the LVM metadata from the disk.

If the device uses multipathing, run multipath -l and note all the paths to the device. Afterwards, remove the multipathed device using multipath -f device.

Run blockdev –flushbufs device to flush any outstanding I/O to all paths to the device. This is particularly important for raw devices, where there is no umount or vgreduce operation to cause an I/O flush.

Remove any reference to the device's path-based name, like /dev/sd, /dev/disk/by-path or the major:minor number, in applications, scripts, or utilities on the system. This is important in ensuring that different devices added in the future will not be mistaken for the current device.

Finally, remove each path to the device from the SCSI subsystem. To do so, use the command echo 1 > /sys/block/device-name/device/delete where device-name may be sde, for example.

Another variation of this operation is echo 1 > /sys/class/scsi_device/h:c:t:l/device/delete, where h is the HBA number, c is the channel on the HBA, t is the SCSI target ID, and l is the LUN.
