Hi,

If you see the symdev show of the devices you would see that the "Device Config" shows as BCV, but when you see the "Back End Disk Director Information" in the same command,it would only show which RAID type it belongs to.

Hence symdisk would only show the RAID-type of the devices..(eg: RAID-1)

If you like to find the BCV devices which are part of the disk, please use the following command

# symdev list -bcv -sid XXX | grep DA:IT

eg:

# symdev list -bcv -sid XXX | grep 0054

0054 Not Visible            ???:? 08C:D4 2-Way BCV Mir Asst'd       RW     501

# symdisk show 08C:D4 -sid XXX| grep 0054

    2   300 FBA              0054 RAID-1         1   1  Ready               511

# symdev list -bcv -sid XXX | grep 08C:D4

0054 Not Visible            ???:? 08C:D4  2-Way BCV Mir Asst'd       RW     501

03C8 Not Visible            ***:* 08C:D4  2-Way BCV Mir N/Asst'd     RW     501

Hi parthi_83,

Do you mean the hotspare invoked on you failed disk?  BCV is logical device in your array which associating your symm dev. You can use command to check the relationships

symbcv list -sid xxx dev

Commands for BCV's:

*symmir list - list all sessions with TF/Mirror relationships.
*List all devices with 'INVALID' state.

Give the list to the customer and, depending on the current state of the session, the customer will need to do one of the following.

If the devices are Established:

*symmir 'split' -force
*symmir 'cancel' -force
*Full Establish

If the devices are Split:

*symmir 'cancel' -force
*Full Establish

The issue is still appearing many volumes, but there's any volumes we can finally establish with this sequence:

split -symforce

cancel

unhold

establish -full
