Zamena FC kartice na Unix-u
Dakle ako vam je na Unix serveru crkla FC kartica, i ona mora da se menja, kako proveriti sve putanje ka diskovima koje idu preko nje.
1. Proveriti da li su sve prisutne FC kartice i “uzete” od strane OS-a :
>ioscan -fnC fc
Class I H/W Path Driver S/W State H/W Type Description
===================================================================
fc 0 0/0/10/1/0 td CLAIMED INTERFACE YY Tachyon XL2 Fibre Channel Mass Storage Adapter /dev/td0
fc 1 0/0/12/1/0 td CLAIMED INTERFACE YY Tachyon XL2 Fibre Channel Mass Storage Adapter /dev/td1
2. Proveriti po pojedinačnim katicama, da li vide mrežu i lepo rade :
>fcmsutil /dev/td0
Vendor ID is = 0x0010bb
Device ID is = 0x0010nn
XL2 Chip Revision No is = 2.3
PCI Sub-system Vendor ID is = 0x0010bb
PCI Sub-system ID is = 0x00128c
Topology = PTTOPT_FABRIC
Link Speed = 2Gb
Local N_Port_id is = 0x0b0400
N_Port Node World Wide Name = 0x50060b0000813f31
N_Port Port World Wide Name = 0x50060b0000813f30
Driver state = ONLINE
Hardware Path is = 0/0/10/1/0
Number of Assisted IOs = 19765403
Number of Active Login Sessions = 2
Dino Present on Card = NO
Maximum Frame Size = 2048
Driver Version = …..
3. Proveriti da li server po HW putanji kroz novu FC karticu vidi diskove na storidžu :
>ioscan -fnH 0/0/10/1/0
Class I H/W Path Driver S/W State H/W Type Description
======================================================================
fc 0 0/0/10/1/0 td CLAIMED INTERFACE HP Tachyon XL2 Fibre Channel Mass Storage Adapter /dev/td0
fcp 2 0/0/10/1/0.11 fcp CLAIMED INTERFACE FCP Domain
ext_bus 12 0/0/10/1/0.11.0.0.0 fcparray CLAIMED INTERFACE FCP Array Interface

/dev/dsk/c12t0d3 /dev/rdsk/c12t0d3
…..
4. I na kraju proveriti da li VG vidi sve pripadajuće diskove :
>vgdisplay -v vgXXX
…..
PV Name /dev/dsk/c12t0d6
PV Name /dev/dsk/c13t0d6 Alternate Link
PV Name /dev/dsk/c15t0d6 Alternate Link
PV Name /dev/dsk/c16t0d6 Alternate Link
PV Status available
Total PE 6079
Free PE 39
Autoswitch On
Proactive Polling On
