So, you create a /dev/md0 from /dev/sdc /dev/sdb disks.
You mount it via mount command and add into /etc/fstab.

After reboot (all disks are inside), everything works as expected (mounted and healty).
You poweroff the box, and remove one of the disks from array.
Booting up everything is fine, except lacking one disk you removed.

After you poweroff and replug the drive, power on, there should be still one disk in the md setup. The one you didn't touch should still be part of md device.
Is this correct ?

Point being, if you unplug the drive, that drive is not considired part of array anymore.
When you plug it back, it will not magically rebuild, this has to be done by hand.
And of course, if you plug the other one out, and leave the first one in, you will not have a working md array.

Peasant.
You are right.
I added it to md0 manually, thats not a problem. Problem is why my data from /mnt/raid is not accessible and i cant read it when i unplug one of the 2 devices?
Thats strange from me, i cant figure out.
I added a folder in array in which i have mounted /dev/md0.

so i have a folder
/mnt/raid/test
and inside test some files.
I cant access it and all is fine. When I unplug disk when machine is running(or not, its the same result), i cant read from that test folder.
Input output error gives me.
But when I unplug another disk, it is working just fine.
Thats what bothers me.
Idea behind all this is to have a shared folder and prevention of data loss. If that disk fails i cannot access to that files. Thats the problem

NAME
pcata - PCMCIA ATA card device driver SYNOPSIS
pcata@socket#:a -u pcata@socket#:a -u,raw The PCMCIA ATA card device driver supports PCMCIA ATA disk and flash cards that follow the following standards: o PC card 2.01 compliance (MBR+fdisk table required for all platforms). o PC card ATA 2.01 compliance. o PC card services 2.1 compliance. The driver supports standard PCMCIA ATA cards that contain a Card Information Structure (CIS). For PCMCIA, nodes are created in /devices that include the socket number as one component of the device name referred to by the node. However, the names in /dev, /dev/dsk, and /dev/rdsk follow the current conventions for ATA devices, which do not encode the socket number in any part of the name. For example, you may have the following: +------------------------+---------------------------+---------------------+ | Platform | | | +------------------------+---------------------------+---------------------+ |/devices name | | | +------------------------+---------------------------+---------------------+ +------------------------+-/dev/dsk-name-------------+---------------------+ |/devices/isa/pcic@1,3e0 | | | +------------------------+---------------------------+---------------------+ |/disk@0:a | | | +------------------------+---------------------------+---------------------+ +------------------------+-/devices/iommu@f,e0000000-/sbus@f,e0001000-/SUNW, pcmcia@3,0 /disk@0:a |SPARC | | /dev/dsk/c1d0s0 | | | | | | | | | +------------------------+---------------------------+---------------------+ PRECONFIGURATION
If a PC Card ATA device is recognized, the pcata driver is automatically loaded, IRQs allocated, devices nodes created, and special files created (if they do not already exist). Known Problems and Limitations o vold does not support pcata. File systems must be mounted manually. o You need to umount the file system before removing the disk. o The ufs file systems on removable media (PC Card ATA) should have one of the onerror={panic, lock, umount} mount options set. CONFIGURATION
Configuration topics include initial installation and configuration, identifying an unrecognized device, special files and hot-plugging. Initial Installation and Configuration 1. Install the Solaris software. 2. Boot the system. 3. Insert the PC card ATA device. Identifying an Unrecognized Device If you insert a PC card ATA device and it is not recognized (no special files created), use the prtconf command to identify the problem. 1. Run the prtconf -D command to see if your pcata card is recognized. (A recognized device will appear at the end of the prtconf output. For example: # prtconf -D . . . pcic, instance #0 (driver name: pcic) . . . disk, instance #0 2. If pcata does not appear in the prtconf output, there is a problem with the PC card adapter configuration or with the hardware. Check to see whether the problem is with the card or the adapter by trying to use the card on another machine and by seeing if it works on the same machine using DOS. Special Files For PC card devices, nodes are created in /devices that include the socket number as one component of a device name that the node refers to. However, the /prtc/dev names and the names in /dev/dsk and /dev/rdsk do follow the current convention for ATA devices, which do not encode the socket number in any part of the name. Hot-Plugging o If you want to remove the disk, you must unmount the file system. o Use the mkfs_pcfs(1M) command to create a pcfs file system: # mkfs -F pcfs /dev/rdsk/c#d#p0:d o To mount a pcfs file system, type: # mount -F pcfs /dev/dsk/c#d#p0:c /mnt o If you want to create a ufs file system, use the newfs command and type: # newfs /dev/rdsk/c#d#s# o To mount a ufs file system, type: # mount -F ufs /dev/dsk/c#d#s# /mnt o To create a Solaris partition, run the format command and go to the Partition menu. For more information, see the format(1M) man page. /kernel/drv/pcata pcata driver See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE | +-----------------------------+-----------------------------+ |VALUE | | +-----------------------------+-----------------------------+ |Availability |SUNWpsdpr | +-----------------------------+-----------------------------+ format(1M), mount(1M), newfs(1M), pcmcia(7D), attributes(5), pcfs(7FS) 20 Oct 2000 pcata(7D)
