HMC CLI zamena za Java konzolu

August 11th, 2010 No comments

Java konzola na hmc web gui-u ume da smara na različitim browser-ima, pogotovu ukoliko isti koristiti na linux operativnom sistemu. Da se ne bi smarali sa različitim verzijama jave svaki put kad reinstralirate ili updejtujete vašu mašinu, konzolu pored jave i serijskog možete dobiti i preko ssh. p.s. da bi izašli iz konzole otkucajte ~. (sa tačkom).

Evo kako:

pSeries – Impending Cache Battery Pack failure

March 18th, 2010 No comments

This is how your pSeries (P5 570) will look like after you get following error notice: “Impending Cache Battery Pack failure.” It is a raid controller battery error. Since it’s located in the middle of the pSeries block, you will end up like we did. Also plan arround 3 to 4h downtime aswell. A bad design by IBM, and lot of “fun” for us. Check out gallery.

AIX 6.1 inovacije

June 3rd, 2009 No comments

AIX 6.1 a možemo naći u 2 verzije: standardna u kojoj se nalazi samo osnovni AIX i enterprajz verzija koja dolazi sa WPM-om (Workload partition manager) i nekoliko Tivoli modula. Fokusiraćemo se na ovu drugu. Skorašnje inovacije koje prate AIX 6.1 su:

  • WPARs (Work load partitions): Virtuelizacija na nivou operativnog sistema u potpunosti podržana od strane Power hardware-a, donekle slična Solaris containers tehnologiji, omogućuje kreiranje višestrukih AIX 6.1 okruženja u okviru jedne AIX  6.1 instance. Aplikativni WPAR-ovi koji mogu biti pokrenuti unutar tkz. globalne instance mogu biti kreirani za par sekundi što omogućuje brzo testiranje aplikacija pre puštanja u produkciju.
  • Live partition mobility: Omogućava premeštanje particija sa jednog sistema na drugi bez restartovanja aplikacija ili bilo kakvog prekida u pružanju servisa kranjim korisnicima. Pored toga omogućuje konsolidaciju resursa kako bi se smanjila nepotrebna potrošnja istih u periodima slabije iskorišćenosti ili prilikom održavanja samih servera.
  • Konkurentni update AIX 6.1 kernela: omogućuje update sistema bez potrebe da se isti resetuje kako bi se primenile izmene.
  • Dynamic tracing: olakšava debugovanje sistema ili aplikacije
  • Enhanced functional recovery routine: set instrukcija koje prate rad sistema i u slučaju problema ili grešaka koje bi inače mogle da obore sistem iste zamrznu i omoguće nastavak rada samog sistema.
  • AIX 6.1 dolazi sa predefinisanim setom tjuning parametara kako bi se izvukao maksimum iz sistema.
  • Updateovan NIM sada podržava NFS v4
  • Nova IBM Director konzola za AIX 6.1

Što se tiče bezbednosti AIX operativnog sistema takođe su uvedene neke novine:

  • RBAC (Role-Based Access Control) rutine
  • Trusted AIX 6.1 sada pokriva sve USA gov. bezbednosne standarde i zahteve
  • Enkripcija JFS fajl sistema kroz jače algoritme i povećan nivo bezbednosti.
  • Mogućnost čuvanja bezbednosnih polisa i templejta u LDAP-u.
  • Minimum aktivnih servisa prilikom prve instalacije

Za više detalja evo nekoliko linkova:

Progres kodovi IBM P serija

June 3rd, 2009 No comments

Za slučaj da nekome zatreba kao meni, ako tražite način da utvrdite šta se dešava u kom momentu prilikom podizanja mašine evo linkova ka IBM sajtu za većinu progres kodova koji vas mogu interesovati. Progres kodovi (tkz. Reference code) koji se pojavljuju prilikom podizanja IPL-a (Initial Program Load) na IBM P seriji (uglavnom su 8 karaktera sem ukoliko to nije drugačije naznačeno). Par primera ovih kodova bi bio:  C1202000, C2001000, C600407E, C7004091 itd. Ovi kodovi mogu biti prikazani na HMC konzoli prilikom podizanja, reboot-a ili shutdown-a particije, a grupišu se u nekoliko celina u zavisnosti od segmenta koji sistem ispituje:

Prezentacija P serije na IBM skupu

March 18th, 2009 No comments

13/12/2007 godine na IBM skupu “System P, recommended hardware for SAP” u Colonial Sun-u održao sam predavanje na temu “IBM Customer story – DELTA M Transition to enterprise”. Govorio sam o IBM P seriji, DS8300 enterprajz storage-u, virtuelizaciji, problemima na koje smo naišli tokom tranzicije itd. Prezentaciju u Power Point-u možeš preuzeti sa mog sajta. Slike sa ovog skupa su ovde i ovde.
