TIPS Solaris 8, 9, 10


I came across this issue while installing the patch on Solaris 8, 9, 10. This happened at the customers environment. Finally came across the root cause for why it fails.

If you also run into the same problem. Please try the following.

It seems, that at some point the patchadd process does an su to the install user if one exists, otherwise to user nobody. If the patch files and all parent directories are not readable by either install or nobody, you get the above mentioned error message.

So there are two workarounds:

1. Setting execute permission for all on /var/spool/patch so that the user nobody can read all patch files and execute a pwd in the patch directory hierarchy.

2. Add an account "install" to the system

useradd -u 0 -o -g 1 -c "Install user" -d / -s /bin/true install

In my case, option 2 worked for the customer.

Habilitar Basic Security Module en Zonas No Globales


1.- La auditoria C2 tiene que estar habilitada ya en la zona global como normalmente se habilita.

2.- En la zona Global ejecutamos el siguiente comando:

# /usr/sbin/auditconfig -setpolicy +perzone

3.- Agregamos la siguiente linea al archivo para que al reboot, la politica de auditoria por zonas se habilite.

echo "/usr/sbin/auditconfig -setpolicy +perzone" >> /etc/security/audit_startup

4.- Nos conectamos a la zona no global y habilitamos el servicio.

# svcadm enable auditd

5.- Validamos que el demonio de la auditoria C2 levante en la zona no global.

# ps -fe | grep audit

NOTA: tomar en cuenta que al habilitar la auditoria c2 comenzaran a generarse los archivos de la auditoria por lo que el espacio de la zona no global debe de ser suficiente para no tener el problema de saturar el filesystem de la zona.

Need unzip fix available in patch utilities patch to unzip Solaris 10 Clusters


A fix to the unzip utility is available in recent patch utility patch revisions. This fix is required in order to be able to successfully unzip very large files such as the Solaris 10 Recommended and Sun Alert Patch Clusters.

Please download the latest revision of the patch utilities patch first and install it, before attempting to unzip the Solaris 10 Recommended or Sun Alert Patch Clusters.
The fix was incorporated in the putback to CRs 6344676 and 6464056.

The following are the earliest revisions of the patch utilities containing the fix:

* Solaris 10 SPARC: 119254-46 or above
* Solaris 10 x86: 119255-46 or above
* Solaris 9 SPARC: 112951-14 or above
* Solaris 9 x86: 114194-11 or above
* Solaris 8 SPARC: 108987-19 or above
* Solaris 8 x86: 108988-19 or above

Without the fix to unzip provided by the above patches, the following error will be seen when attempting to unzip the Solaris 10 Patch Clusters:

# unzip -q 10_Recommended.zip
note: didn't find end-of-central-dir signature at end of central dir.
(please check that you have transferred or created the zipfile in the
appropriate BINARY mode and that you have compiled UnZip properly)

In addition, do not unzip Solaris patch clusters on Windows. Solaris patch clusters, and solaris patches more generally, can contain case-sensitive file names. Consequently clusters and patches must be unzipped on a case-sensitive filesystem (corruption can occur if unzipping on filesystems that are not case-sensitive).

To make the secondary disk bootable Solaris X86.

Once all file systems are attached and all the metadevice status are "OKay".
Then, update the secondary disk booteable.


The installgrub utility will update the Master Boot record of the secondary disk, so that it can be bootable.
Example:
root # installgrub -fm /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/c0t3d0s0
stage1 written to partition 0 sector 0 (abs 16065) stage1 written to master boot sector
root #

Now update the secondary disk as alternate bootpath in /boot/solaris/bootenv.rc file, this can be done by executing the eeprom command


root@rmanair01 # ls -la /dev/dsk/c0t3d0s0
lrwxrwxrwx 1 root root 78 Mar 31 2009 /dev/dsk/c0t3d0s0 -> ../../devices/pci@0,0/pci8086,2545@3/pci8086,1460@1d/pci8086,341a@7,1/sd@3,0:a

Example:

root@rmanair01 # eeprom altbootpath="/pci@0,0/pci8086,2545@3/pci8086,1460@1d/pci8086,341a@7,1/sd@3,0:a"
root@rmanair01 #


Many software packages can be downloaded in the form of an ISO image

Mount the image directly into the filesystem using the lofiadm and mount commands.

Given an ISO image in /export/temp/software.iso, a loopback file device (/dev/lofi/1) is created with the following command:

lofiadm -a /export/temp/software.iso /dev/lofi/1

The lofi device creates a block device version of a file. This block device can be mounted to /mnt with the following command:

mount -F hsfs -o ro /dev/lofi/1 /mnt

These commands can be combined into a single command:

mount -F hsfs -o ro `lofiadm -a /export/temp/software.iso` /mnt

root # powermt set policy=co dev=all # CLARiiON, VNX OE
root # powermt config
root # powermt save

Display High Level HBA I/O Paths

root # powermt display

Display All Attached LUNs

root # powermt display dev=all

Display specific LUN

When there are multiple LUNs connected to a server, you might want to view information about a specific LUN by providing the logical name of the LUN
root # # powermt display dev=emcpowera <== "Pseudo name"

Display PowerPath HBA Mode

Displays whether hba is enabled or not in the column Mode.
root # powermt display hba_mode

root # Display available I/O Paths.

Displays all available path for your SAN device.
root # powermt display paths

Display Port Status

Displays the status of the individual ports on the HBA. i.e Whether the port is enabled or not.

Check the I/O Paths

If you have manually removed an I/O path, check command will detect a dead path and remove it from the EMC path list.
root # powermt check

Forcefully set the mode for a specific HBA

You can change the mode of a specific HBA to either standby or active
# powermt set mode=standby hba=1

Delete an I/O Path

Use this command to remove any specific I/O path (or) a whole device.
# powermt remove dev=sdd <== "I/O Path"

Configure PowerPath

This command checks for available EMC SAN logical devices and add those to PowerPath configuration list. Powermt config command, sets some of the options to it's default values.
# powermt config

Make Dead I/O Path Alive

If you have dead I/O paths, and if you've done something to fix the issue, you can request PowerPath to re-check the paths and mark it as active using powermt restore command.

# powermt restore dev=all

Save the current Powerpath Configuration

To backup the current PowerPath Configurations.

# powermt save
This will save the current powermt configuration to /etc/powermt.custom file.
To a specific file
# powermt save file=/etc/powermt.18-Feb-2011
