Before you start resyncing ensure that c0t2d0s0 and c0t3d0s0 are equal in size!
The suggested command is if you have an additional new disk (that is very unlikely to ever be the case).
For in-place replacement use
It will automatically resync.
Just reading you have tried that. I guess the c0t2d0 disk has a bad sector i.e. is broken. Because only the vol manager software has detected the fault it would have to change the disk LED but this feature is not implemented.
Thanks for the answer MadeInGermany,
so i must replace the disk right? but how i know which disk must be replaced when all disk led is green?
Being somewhat extremely new to Unix, I have just had a system crash

How do I switch to use the mirrored copy?
Any assistance greatly appreciated

I have 2 drives on a sun solaris 8 server that is a live server. I am putting in an additional 2 drives and want to mirror the the first 2. I was thinking of using disksuite but one drive is the root drive with 1 maybe 2 free paritions. The other is only one partition (36G). I was wondering... (2 Replies)
Hello,
I've got 2 system disks (hdisk0 and hdisk1) in the mirror (RAID1) on AIX 5.3. Since the hdisk1 makes some troubles, we want to replace it with the new one. How can I disable this hdisk1 disk and prepare the mirror to use the new physical disk? As far as I know, I must remove disk from the... (3 Replies)
Hi,
I want to know if one disk is failed in mirror in solaris and system is booted from another disk, is it possible to find out from which disk system is booted at command level? (1 Reply)
I have a SUN 440 running Solaris 8 that is generating funny errors on /dev/dsk/c1t0d0 and I would like to dupe the drive(the non offending drives are removed for this process), swap it with the dupe and reboot. From what I have read, the process seems simple:
dd if=/dev/dsk/c1t0d0... (1 Reply)

What I would like to do is break the mirror, pull the first... (2 Replies)

Mirror/redirect action in tc(8) Linux Mirror/redirect action in tc(8)NAME
mirred - mirror/redirect action
SYNOPSIS
tc ... action mirred DIRECTION ACTION [ index INDEX ] dev DEVICENAME
DIRECTION := { ingress | egress }
ACTION := { mirror | redirect }
DESCRIPTION
The mirred action allows packet mirroring (copying) or redirecting (stealing) the packet it receives. Mirroring is what is sometimes
referred to as Switch Port Analyzer (SPAN) and is commonly used to analyze and/or debug flows.
OPTIONS
ingress
egress Specify the direction in which the packet shall appear on the destination interface.
mirror
redirect
Define whether the packet should be copied (mirror) or moved (redirect) to the destination interface.
index INDEX
Assign a unique ID to this action instead of letting the kernel choose one automatically. INDEX is a 32bit unsigned integer greater
than zero.
dev DEVICENAME
Specify the network interface to redirect or mirror to.
EXAMPLES
Limit ingress bandwidth on eth0 to 1mbit/s, redirect exceeding traffic to lo for debugging purposes:
# tc qdisc add dev eth0 handle ffff: ingress
# tc filter add dev eth0 parent ffff: u32
match u32 0 0
action police rate 1mbit burst 100k conform-exceed pipe
action mirred egress redirect dev lo
Mirror all incoming ICMP packets on eth0 to a dummy interface for examination with e.g. tcpdump:
# ip link add dummy0 type dummy
# ip link set dummy0 up
# tc qdisc add dev eth0 handle ffff: ingress
# tc filter add dev eth0 parent ffff: protocol ip
u32 match ip protocol 1 0xff
action mirred egress mirror dev dummy0
Using an ifb interface, it is possible to send ingress traffic through an instance of sfq:
# modprobe ifb
# ip link set ifb0 up
# tc qdisc add dev ifb0 root sfq
# tc qdisc add dev eth0 handle ffff: ingress
# tc filter add dev eth0 parent ffff: u32
match u32 0 0
action mirred egress redirect dev ifb0
