■ Section 4.5.1, “Dynamic Reconfiguration Related Problems” on page 4-10

■ Section 4.5.1.1, “Workaround” on page 4-10

Solaris device numbers for controllers, the c number in /dev/[r]dsk/cXtYdZs0,

are assigned by Solaris during reconfiguration reboots or device addition. It is not

always easy to predict how and when device numbers will be re-allocated after a

reconfiguration boot is done following configuration changes.

If this happens unexpectedly, mount points in /etc/vfstab and in Volume

Manager can be lost. The file /etc/path_to_inst is intended to keep device

numbers the same across normal reboots. Bug 4118532 describes numerous details,

but note the following:

■ Do not start any software installation of RAID Manager 6 or Solaris without first

making sure that the device names are stable. See FIN I0727.

A reconfiguration reboot is the best way to do this. Device numbering is likely to

change if hardware has been added, removed or disabled. Prior to Solaris 7, if one

did a reconfiguration boot with a failed controller, the C number was lost because
