Reboot causes disks in Resync State

Dear Team,

This time i am facing some new problems which is beyond my thinking. I need some expert advice.

We are having 4 Servers ( 2 nos Sun SPARC Enterprise T5220 & 2 nos of SF e2900 Servers ). Both the T5220 Servers are Termed as Node A and Node B . The same things are followed with E2900 servers.

PROBLEM OCCURED:

-> i have noticed many times whenever i am rebooting (init 6 or reboot ) any node of SF T5220 ,after rebooting the sub-mirrors are going to need maintance state. Once i run metasync command, after 20-25 min all the sub-mirrors are coming to Okay State.

But if am using the command 'init5' and then do the poweron from sc> things are okay means all the sub-mirrors are in okay state, no need maintance state occured

-> At the same time,if i follow the above process with any of the SF e2900 server,there i am not found any need maintance state.It is booting normally and all the sub-mirrors are in okay state in one go.

NOTE:The same applications are running in all the nodes.

My doubt is why this "need maintance" state only arises whenever i reboot any T5220 server. I found it hard to lacate the proper cause to this ???

please help.

Regards
Sudhansu

NAME

       install-solaris - install the Solaris operating system

SYNOPSIS

       install-solaris

       install-solaris	invokes  the  Solaris  Install	program. Depending on graphical capability and available memory at the time of invocation,
       install-solaris invokes either a text-based installer or a graphical installer.

       The following minimum requirements for physical memory dictate which features are available during installation:

       For SPARC machines:

       128 MB

	   Minimum physical memory for all installation types

       128 MB

	   Minimum physical memory required for windowing system

       384 MB

	   Minimum physical memory required for graphical-based installation

       For x86 machines:

       256 MB

	   Minimum physical memory for all installation types

       256 MB

	   Minimum physical memory required for windowing system

       512 MB

	   Minimum physical memory required for graphical-based installation

       In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number  of  fea-
       tures available.
