Do you mean, do a consistency check of filesystem?

To do consistency check on filesystem you can use
the fsck command

sytax is
use fsck with filesystem
eg

fsck /dev/dsk/c0t0d???

or

use fsck with mount point
eg

fsck /usr

or
just do fsck without specifing any filesystem or mount point.
eg
fsck
 
pwck(8) 						      System Manager's Manual							   pwck(8)

NAME
pwck, grpck - Checks the password and group files for inconsistencies SYNOPSIS
pwck [-admNs] [file] grpck [-mNp] [file] FLAGS
Causes both pwck and grpck to additionally check the NIS database entries using the same consistency tests. Users that are defined in the local password or group file without the "+" at the start of the name field are flagged as duplicate entries. pwck Inhibits the running of the /tcb/bin/authck -p command on a system running Enhanced Security. Prevents pwck from checking for the presence of the user's login directory. Directs pwck to check for mixed case usernames. Causes pwck to check for the presence of the optional shell field for each entry. grck If there are no members, causes grpck to display a message indicating the listed group has no members. Directs grpck to not check for a users' existence in the password database (local or NIS). DESCRIPTION
The pwck command scans the /etc/passwd file, or the named file, and writes to standard out any inconsistencies. The scan checks the number of fields, login name, user ID, group ID, and existence of a login directory and optional program name. The grpck command scans the /etc/group file, or the named file, and writes to standard out any inconsistencies. The scan checks the number of fields, group name, group ID, and whether all login names appear in the password file. EXAMPLES
To verify the password information in the /etc/passwd file for consistency, enter: pwck To verify the password information in the /etc/passwd file and the NIS database for consistency without checking each users login directory validity, enter: pwck -Nd To verify the group information in the /etc/group file and the NIS database for consistency, enter: grpck -N FILES
