VXVM not started/ VXVM disabled during boot

Many times we get error like VXVM not started in Solaris 10.
To correct this problem, follow to remove the below file.
 rm /etc/vx/reconfig.d/state.d/install-db
and reboot the system. VXVM should start now.
Many times vxconfigd is not started manytimes.
bash-3.00# ps -ef|grep vx
    root   748     1   0 20:30:19 ?           0:05 /sbin/vxesd
    root   626     1   0 20:30:13 ?           0:02 vxconfigd -m disable
It does not bring any disk in OS.
bash-3.00# vxdisk list
DEVICE       TYPE            DISK         GROUP        STATUS
bash-3.00# vxdg list
NAME         STATE           ID
To correct this problem, follow below steps:
bash-3.00# vxdctl init <hostname>
bash-3.00#  vxconfigd -kr reset -m boot 
and reboot the system.
After this vxconfigd daemon will come up. and disks do appear now
bash-3.00# ps -ef|grep  vxconfigd
    root  3002     1   0 20:36:17 ?           0:02 vxconfigd -kr reset -m boot
bash-3.00# vxdisk list

Understanding How ZFS Calculates Used Space

This document explains how ZFS calculates the amount of used space within a zpool and provides examples of how various ZFS features affect that calculation. DETAILS A ZFS storage pool is a logical collection of devices that provide space for datasets such as filesystems, snapshots and volumes. A zfs pool can be used as a filesystem, i.e. such as mounting/unmounting; to take snapshots that provides read-only (clones are writable copies of snapshots) copies of the filesystem taken in the past; to create volumes that can be accessed as a raw and a block device and for setting properties on datasets. Interaction of all these datasets and associated properties such as quotas, reservations, compression and deduplication (Solaris 11 only) play a role in how ZFS calculates space usage. Neither the du nor df command have been updated to account for ZFS file system space usage. When calculating zfs space usage, always use the following command. # zfs list -r -o space <pool_name...

How To Verify Remote System Controller (RSC) is Configured and Current on Sun Fire[TM] 280R/V480/V490/V880/V890 servers

Steps to Follow: How To Verify Remote System Controller(RSC) is Configured and Current 1.Check to see if the RSC software is already installed. # /usr/bin/pkginfo | grep SUNWrsc 2.If the software is installed the command should output the package name and info.   The version of the package installed in Solaris should match the version of firmware installed on the card.   `rscadm version` in Solaris will display the firmware version. 3.If the software is not installed the packages can be found on the supplemental CD that came with the Solaris Operating Environment. If you do not have the CD the software can be downloaded from MOS: RSC 2.2.2 is supported with Solaris 10, but you need to get this from a supplemental CD (for Solaris 9, since there is no supplemental CD for S10). The packages for Solaris 8 and 9 (and later) are both in the zip file. There are two options of the zip file, 32bit, and 64bit, but they both have the same checksums, so there are...
