Maint, resyncing and last-erred notifications
Hi fellow members!

I have a oracle solaris server with two internal disks, that acts as an authentication server only, and for now the server seems to be doing its job, but when typing metastat -c I get some notifications.
I am not familiar with SVM, I wonder if someone can help me on this:
Code:
metastat -c
d50              m  8.0GB d51 d52
    d51          s  8.0GB c0t0d0s6
    d52          s  8.0GB c0t1d0s6
d30              m   89GB d31 (maint) d32 (maint)
    d31          s   89GB c0t0d0s5 (resyncing)
    d32          s   89GB c0t1d0s5 (last-erred)
d20              m   16GB d21 d22
    d21          s   16GB c0t0d0s1
    d22          s   16GB c0t1d0s1
d10              m   15GB d11
    d11          s   15GB c0t0d0s0
d60              m  8.0GB d61 d62
    d61          s  8.0GB c0t0d0s7
    d62          s  8.0GB c0t1d0s7
d12              s   15GB c0t1d0s0

and the output of iostat -E shows me:

Can you help

This disk c0t1d0 is experiencing read errors.

Currently it is only evident on slice 5 to the SVM.
iostat is showing errors for entire device.

Have a replacement disk ready.

Detach all slices from metadevices involving failed disk (c0t1d0..)
You will need to identify the disk physically and unconfigure it using cfgadm

The blue led should indicate the disk is safe to remove.

Replace of faulty disk in the server.

After the new working disk is inserted and visible to the operating system, proceed and follow the docs regarding svm replace faulty disk (or root disk) and its slices.

You might also want to considering making backup asap.

This is no easy task, and should be performed with care.
Verify each step taken and follow the documentation for the exact version of SVM and operating system you are using.

Hope that helps.
Regards
Peasant.

thanks for your help, but I can only proceed if I have a spare/replacement disk, but for the moment I should backup all data on disks right? Would a backup be reliable when there is media or read errors?

Since other device in the mirror is ok, the answer is yes, the backup should be reliable.

Be vary tho, the d12 metadevice is not mirrored (and its slice belongs to faulty disk).
Is that swap ?

Peasant.
