SC and SMS command may useful.... Just a notes

Following list of SC and SMS command may useful during field intervention:

1. Reset CHS with SMS
# showchs -v -c sb10
# setchs -s OK -r "Now its Okay" -c sb10/P0

2. Shutdown domain gracefully (init 0) from SC (tested on SF15K platform)
# setkeyswitch -y -d Domain_name standby

3. .postrc file owner and permission

/etc/opt/SUNWSMS/SMS.x.x.x/config/Domain_Name/.postrc ==> [rw-r--r--] root/sms

4. .postrc ==> "allow_us3_cpus"
allowing old CPU model into domain (mixed cpu type)

5. Allowing hpost without IO board (useful during SB test/diagnostic)
# cat .postrc

no_ioadapt_ok
no_obp_handoff

Veritas Volume Manager frequent use command.... vxdiskadm, etc

1. vxdiskadm

The vxdiskadm utility is a text menu driven (script menu). Most of disk administration can be done through this menu. Its including disk initialization, add, encapsulate, mirror volume, import and deport disk group, and even for disk maintenance such as disk removal or replacement and many more. This script is intended primarily for users who wish to use a simple method for doing common operations, and for users who understand only a limited set of concepts.

root@sun1: # vxdiskadm

Select an operation to perform:

2. vxdctl

The vxdctl utility manages some aspects of the state of the volume configuration daemon (vxconfigd).

root@sun1: # vxdctl enable

This operations request that vxconfigd enter enabled mode, import all disk groups, and rebuild the volume and plex device node directories. This operation can be used even if vxconfigd is already in enabled mode. The primary purpose for using this operation when in enabled mode is to rebuild the volume and plex device nodes. This operation will also cause vxconfigd to scan for any disks that were newly added since vxconfigd was last started. In this manner, disks can be dynamically configured to the system and then recognized by the Volume Manager. This command should be executed during disk reconfiguration (disk add).

3. vxdg

The vxdg utility performs basic administrative operations on disk groups. Operations include list of diskgroup, creation of disk groups, the addition of disks to a disk group, disk group imports and deports, etc

root@sun1: # vxdg list

4. vxdisk

The vxdisk utility performs basic administrative operations on disks such as list information, initializing, replacing disks, etc.

root@sun1: # vxdisk list

5. vxedit

The vxedit utility sets and changes various attributes for Volume Manager configuration records that do not depend upon volume usage types.

root@sun1: # vxedit -g datadg set failing=off disk_ext
This operation will clear the failing flag when a vxdisk list status shows "online failing"
Before executing the command:
root@sun1: # vxdisk list
DEVICE TYPE DISK GROUP STATUS
c1t0d0s2 sliced rootdisk rootdg online
c1t1d0s2 sliced rootdg00 rootdg online
c3t40d0s2 sliced disk_ext datadg online failing
After executing the command:
root@sun1: # vxdisk list
DEVICE TYPE DISK GROUP STATUS
c1t0d0s2 sliced rootdisk rootdg online
c1t1d0s2 sliced rootdg00 rootdg online
c3t40d0s2 sliced disk_ext datadg online

vxedit set nohotuse=(on/off) [disk_name]
This operation will set/reset the nohotuse flag (hot spare/hot relocation) for particular disk.

6. vxassist

The vxassist utility is an interface to the VERITAS Volume Manager that finds space for and creates volumes, adds mirrors and logs to existing volumes, extends and shrinks existing volumes, provides for the migration of data from a specified set of disks, and provides facilities for the on-line backup of existing volumes.

root@sun1 # vxassist -g datadg maxsize
Maximum volume size: 186730496 (91177Mb)
root@sun1 # vxassist -g datadg make datavol10 500m disk_ext
This operation is creating volume datavol10 with size equal 500m on disk disk_ext (c3t40d0)

7. vxprint

The vxprint utility displays complete or partial information from records in Volume Manager disk group configurations.

root@sun1 # vxprint -ht
