5.1 Notes

This section describes notes when exchanging and extending PCI cards by using PCI Hot Plug feature.

5.1.1 Network driver configuration changing 

In case of configuring parameters in driver.conf(4) file and replacing or extending the PCI card by using the PCI Hot Plug feature, parameters which configured in driver.conf(4) file may not be valid.

To change the initial parameters after the PCI card being replaced or extended by using PCI Hot Plug feature, please refer to the solution of each PCI card shown below. (Each PCI card manual (*1) has the description of setting by the ndd command. Please refer it.)

Product ID (Functions)	Software of driver	Resolution
X1033A-U X1033A-X (10/100BASE-T)	Solaris OE(hme)	Please make a setting by the ndd command. Or please reboot a system after changing the /kernel/drv/hme.conf file.
PW008FE1 (10/100BASE-T)	FUJITSU PCI 10/100 Ethernet 1.0 or later (enclosed with a PCI card)	Please make a setting by the ndd command. Or please reboot a system after changing the /kernel/drv/fjfe.conf file.
PW008QE1 (10/100BASE-T x 4)	FUJITSU PCI Quad 10/100 Ethernet 1.0 or later (enclosed with a PCI card)	Please make a setting by the ndd command. Or please reboot a system after changing the /kernel/drv/fjqe.conf file.
PW008QE2 (10/100BASE-T x 4)	FUJITSU PCI Quad 10/100 Ethernet 1.1 or later (enclosed with a PCI card)
PP028GE1U PP028GE1X (1000BASE-SX)	FUJITSU PCI Gigabit Ethernet 1.4.1 or later (enclosed with a PCI card)	The ndd command is not supported. Please reboot a system after changing the /kernel/drv/fjge.conf file.
PW008GE1U PW008GE1X (1000BASE-T)
PW008GE4 (1000BASE-SX)	FUJITSU PCI Gigabit Ethernet 2.0 or later (enclosed with a PCI card)	Please make a setting by the ndd command. Or please reboot a system after changing the /platform/sun4us/kernel/drv/fjgi.conf file.
PW008GE5 (10/100/1000BASE-T)

(*1) In case of X1033A-U(-X), please refer to Sun Microsystems, Inc web page about "Platform Notes: The hme FastEthernet Device Driver" and ndd(1M) man page etc..

5.1.2 Using tape device while PCI Hot Plug operation 

By using the PCI Hot Plug feature, a job which uses tape devices may be terminated abnormally.
While using the PCI Hot Plug feature, avoid using tape devices.

5.1.3 DR operation to shared device (SCSI interface) for cluster system 

If a shared device of non-multipath configuration is connected with a cluster system,

there is a possibility that the following alert messages are displayed in the node

to which the PCI card is not exchanged while exchanging it with which the shared

device is connected by the PCI Hot Plug function.

scsi: WARNING: /pci@MN,M000/scsi@M,N (xxxx):
Connected command timeout for Target x.x

[Example]
scsi: WARNING: /pci@80,4000/scsi@2,1 (glm2):
Connected command timeout for Target 0.0

Or,

scsi: WARNING: /pci@MN,M000/scsi@M,N (xxxx):
Disconnected command timeout for Target x.x

[Example]
scsi: WARNING: /pci@80,4000/scsi@2,1 (glm2):
Disconnected command timeout for Target 0.0

Or,

scsi: WARNING: /pci@MN,M000/scsi@M,N (xxxx):
Disconnected tagged cmd(s) (x) timeout for Target x.x

[Example]
scsi: WARNING: /pci@80,4000/scsi@2,1 (glm2):
Disconnected tagged cmd(s) (1) timeout for Target 0.0

Or,

scsi: WARNING: /pci@MN,M000/xxxx@M,N/xxxx@M,N (xxxx):
SCSI transport failed: reason 'reset': xxxx

[Example]
scsi: WARNING: /pci@80,4000/scsi@2,1/sd@3,0 (sd20):
SCSI transport failed: reason 'reset': retrying command

When these warning message is displayed, the access to the shared device is temporarily

interrupted. But the access is retried and restored automatically by the system.

However, there is a possibility that the access is not restored according to some

conditions. Please stop the access to the shared device connected with the PCI card

during its exchange.

5.1.4 Others 

When expanding PCI cards by using PCI Hot Plug feature, it is necessary to install the device driver (case of file devices) and the driver for using the added PCI card.

When extending PCI cards, each driver consumes memory capacity to control PCI cards.

Please refer to the installation guide attached to each PCI card about memory capacity required in order to extend PCI cards, and installation guide of the redundant configuration software about memory capacity required.
